In your opinion, being black makes it harder to date in what sense? Are you saying other black people aren't dating black people or you don't find that enough non-blacks are dating blacks? If partly the latter, as someone else pointed out, not dating different cultures, or races, by default is not racism.
I would argue that being human makes it hard to date, even more so due to swipe culture, social media and less in person engagement. We are simply complicated creatures on so many mind boggling levels. Being an "ugly" human, visually and/or mentally, makes it even harder to date, and we all deal with that regardless of our shade. Having disabilities or being self defeating adds another layer in making it even harder, but this isn't a competition and each case is unique. I would rather us all approach it as "I am having a problem dating" than "everyone in this certain group is having a hard time dating". One has a better chance of finding a resolution.
Does racism exist along with the plethora of other ism? Absolutely and that will never change. We are human and there is, on average, an innate flaw to that, which I am not sure could ever fully be resolved. For anyone that experiences any form of hate, real or perceived, it has the potential to change them and affect them throughout their lives. Our parents often determine our resiliency and success in life and not everyone is lucky enough to have great parents as role models. It is even worst when people get trapped in negative echo chambers online where algorithms bombard you with a seemingly never ending playlist of whatever travesty you just watched. This could be anything and will give the impression of an epidemic no matter the content. The feedback loop caused by these echo chambers is enough to defeat even the strongest.
Your quote highlights one potential issue, who you are listening to. Certain people will ensure you will never progress. I recommend at least giving some of the following people a listen with an open mind. Thomas Sowells, see video in one of previous posts for Smokey Robison, Larry Elder, Denzel Washington, Morgan Freeman, Officer Tatum, Candice Owens, Anthony Brian Logan, Herman Cain, Don Cheadle and the list goes on. I do not claim these people to be perfect or infallible nor do I agree with everything they say and believe. Then again, that applies to everyone, it is okay to have some disagreements and still appreciate their core beliefs and values. There wouldn't be personal growth if we only dealt with clones of ourselves. These people, which happen to be black if that matters, have a completely different mindset on blacks than what the media, certain political parties and certain race hustlers push.
Keep in mind I am an "average" white male that by some of your descriptions should have me knee deep in the beaver pond. As mentioned elsewhere, a big part of my future demise will be due to loneliness. I say let us stop the competition of who has it worse and who has it better and instead acknowledge we all suffer from it. I am unaware of any group of people that is on the verge of extinction due to no one dating anyone in that group.
Have a wonderful day, beautiful person.
