Fair enough, although I would add that I'm blind to your reality. Reality for me is nothing like it is for you, and I think that's fine. Thank you for answering my questions nonetheless, because it allows me to understand you a bit more.
So you've internalized others' biphobia. Both a certain group of straight and gay/lesbian people do not see bisexuality as valid because they are personally set up to only be attracted to one gender/sex. Under the assumption that everyone must be like that, bi and pansexuality will inevitably be a farce, or a phase that one has to go through before picking a side. Of course, some people who willfully misunderstand what bisexuality is wouldn't want bisexuals around. It can, understandably, be a very painful experience to be left for someone of the opposite sex for both straights and gays/lesbians, so they would rather avoid the potential of being in that situation. Then there's also the perception that a person with a "straight passing" sexuality suffers less than one who is more outwardly outside of the heteronormative with their sexuality, so bisexual and pansexual people will get the same disdain as straight people do in this regard. Pretty sure you even said something to the effect of that elsewhere; "they're not discriminated against enough" for you. So, you and others subconsciously or purposefully seek to be nasty and balance that out.
Now those thoughts are your own, but now what? You're still bisexual, the same type of degenerate trash that you despise. Have you tried to enter a relationship? Or do you just roll
with the assumptions that you will provide someone a bad experience just because of what you see on some subreddits? Do you believe that there are people who have valid positive experiences with bisexual partners? Do you even care about them? What about the people who had bad experiences with gays and lesbians? What do you think bisexuals who have been sexually assaulted or abused in the name of "picking a side" think of gay, lesbian or straight people? Do you think that all lesbians are violent because the rates of domestic violence are on the higher side (yet still less when compared to the rates that bisexual women are abused by their intimate partners) for them? Or, have you not considered anything else because it won't provide you with an excuse to degrade yourself? Has your research gone that far? All of these are rhetorical, really, you can answer some or all but I don't really expect you to answer me. I think you should answer yourself.
By now a lot of people in the community have expressed that they and others believe the opposite of what you think, but that doesn't matter to you, and I guess it doesn't have to. To me, this argument is like saying I went into a subreddit about crime and began to fear people of color because so many people on the internet that I do not know claimed to have been perpetrated by them, and without considering why that may be or why people may be incentivized to say such vile things, I take those words at face value and begin to hate my own race of people. I guess you may put bisexuals on the same tier as racists too, though?
I'm really sorry that you've encountered so many bad experiences and came to believe this. If you want to ctb that's a personal decision, but I don't think you or any other bisexual person deserves to be put to death for a sexuality. There are some people who identify as bisexuals who do hurt others along their journey, either on purpose or by accident, but if you're not using your desire to actively hurt someone, being attracted to both men and women is just who you are. Actions and attractions are so different.
