I think lgbtq people are lowkey toxic.
Why makes you think a whole group of people is toxic?
They seem to be a little too elitist and they believe they're a special kind of people.
Its understandable to expect a group that is supposed to represent tolerance, to be more tolerant. However you shouldn't judge an entire group of people based off interactions with a few of its members. Otherwise you'll end up generalizing  all of them and assuming the worst.
It was a one time thing so why can't I say my two cents?
Because your two cents is a prejudiced statement toward a large group of people. Making assumptions like that is wrong. Try to take a more open approach in your interactions.
