Who is? Individual people are. Not "all straight people". Your experience with some people being raging assholes doesn't mean that all people are raging assholes. A lot of those straight people-who perhaps you've never met-are advocates for the acceptance and rights of gay and trans people. Who push back when someone says something homophobic and shitty. Who write their legislators and go to marches for progress for LGBT rights. Those straight people aren't being cruel and shitty to you. When you graduate, consider moving to a more liberal city where you will be accepted as being gay and you will feel less prosecuted than you feel now. When you interact with more tolerant straight people who are accepting of other lifestyle choices you can come to see not everyone is shitty. If you continue to decide that you want to hate all straight people for being the orientation they were born because you feel that you are being prosecuted, then you will be acting the same as the people who blindly prosecute you for being the orientation you were born. And that's not cool to hate you for, nor is it cool to continue the hate.
