See kids this is a good example of how people who hate things refuse to educate themselves on it to understand what their hating.
Besides the obvious issues with this take(equality doesn't take away from others rights) there is another problem that would jeopardize the idea that lgbtq hate straight relationships. This is that bisexual people exist, and that their right to marry the opposing sex would be under fire if heterophobia is really a thing. But bisexuals are part of lgbtq. And so this cannot be right, this just goes to show you that people that have prejudiced beliefs will not do the tiniest bit of research on it. This shows that they do not actually care about what they preach they just want to hate.
