It's fine for children to be taught sex ed as early as kindergarten. Giving children a basic rundown on sex, along with other things like boundaries and consent, isn't going to traumatize them and may even aid in helping them better recognize when others try to take advantage of them (sexual abuse, sexual assault, molestation, etc).
Debates aren't a reflection of intelligence but rather can be viewed as being more of a performance. They are in no way a good way to tell if someone is right or not. (And I'm saying this as someone who needs to stop being so argumentative)
Swear words shouldn't be viewed as that big of a deal. Most swear words originally were just normal words used by the poor but as people started to try and adopt the words used by the upper class it led to those words becoming stigmatized, with their use now being seen as bad. Swear words are no different from any type of word, so there is no point in making such a big deal over others using them.
You shouldn't have to be expected to write/type things like emails in a formal fashion to people, such as professors. I find it so dumb, especially since it makes it take longer for me to send a simple message to them. My mom says that you have to and one of my professors stated that she wouldn't even bother reading your email if it's typed casually because we needed to learn to write more formally for when we enter the workplace, but why? Why can't I just write something quick that gets to the point? What makes the use of more casual language so bad?
Racial preferences in dating nearly always highlight specific unchecked biases we have about race and shouldn't just be treated as some silly thing that isn't a big deal. People love to talk about being against racism until they are forced to confront their own biases and racist tendencies, and then their true colours show. There isn't any inherent reason to find people of one particular more attractive than the other and making claims like "I'd never date a person of that race" only highlights the fact that you are racist. Racism isn't some simple "I'm a mean evil racist who wants to kill all people" thing. It can be seen in more subtle and normalized things too. If we want to tackle racism then we need to start accepting the fact that most of us have racial biases/racist tendencies and we need to take the time to unlearn them.
The amount of sex and nudity found in shows and movies today isn't that big of a deal. Nudity and sex are a natural part of life and seeing them portrayed more in media isn't a bad thing. The issue is in how they are portrayed. For example, I decided to put on Swarm today while I was busy making breakfast and that show has quite a few scenes that involve sex or nudity but I never found myself uncomfortable watching those scenes. I think a large part of why is because those scenes aren't presented in a pornographic male gaze sort of way. They are instead shown in a way that feels more natural. Those scenes are shot no differently from any of the other scenes in the show. I think that the discomfort we feel towards scenes involving sex and nudity comes from how it's presented rather than from it involving sex and nudity (not in all cases of course, but in a lot of cases).
Being weird isn't a special trait. Everyone is weird. Some people's weirdness is more obvious than others, but every human has their own set of quirks. Along with that, weird is a very subjective thing and the definition of what's "weird" can change due to a variety of factors.
Way too many people seem to be quick to diagnose or explain things by claiming that Person A has X. You especially see this when it comes to shows, books, and movies, where people will just claim that a character has something like autism despite there not being any good evidence to back it up. It's dumb and leads a lot of people overlooking different aspects of the characters and how their experiences have impacted them. All their depth is completely ignored and brushed away when people do this type of stuff. I also hate when people are quick to diagnose others irl. I've already had this happen to me twice (once where people claimed I had PTSD and other time was when my uncle (who doesn't know shit about me) thought I had autism). It's really fucking annoying and people need to stop doing it. It's not helpful, it's just rude. Mental illness isn't always necessary to explain certain behaviours and to throw those diagnoses around all willy-nilly leads to them becoming meaningless.
Parental alienation isn't some big phenomenon and is instead just a term commonly thrown around by abusive parents who want custody of their kids. The term is used to invalidate the feelings and concerns of abused children and has led to many children being put in the care of or being made to interact with their abuser. Actual parental alienation is rare and parental alienation should never have been a term to begin with.
