why are some lgbt+ so annoying?

How can people who don't exist be annoying?

Because some people are annoying, queer or not.

Because each one of them is a person, and some people are annoying.  I has nothing to do with the individual being LGBT+.

Many of them are defensive...especially the "non-binary" portion and the people who claim there's billions of genders or it's okay to sexualize kids. These snowflakes are also stubborn trying to force us to conform to their beliefs. A lot of the LGBTQ community is okay though as there's actually quite a few who agree male and female are the only real genders and it's wrong to sexualize kids. They also often enjoy many of the same things straight people are interested in 

It's not them, it's you. You hold phobic beliefs.
