Do you think there are only 2 genders, or that there is a whole spectrum? Or something in between?

I think there are 2 genders, maybe 3, 3rd gender being "other"

What do you think about non-binarity, pangender, genderfluid, agender, etc.?

As people who self-identify as genderfluid, non-binary, etc. often explain, they sometimes feel girly, sometimes boyish and give the most basic shit as an example. If i want to listen to "I am barbie girl" by Aqua or I like to have flowers at home, or if I like playing dolls with girls in the kindergarten that doesn't make me non-binary somethinggender.

What do you think about gender-neutral pronouns? Do you / Would you use them?

I would not use gender-neutral pronouns in russian, not only does it sound stupid, but it is also very demeaning. Doing so in english would be fine to me, as it doesn't rub me the wrong way, language-wise.

What do you think about gender-neutral bathrooms?

I don't understand where the issue is.

Each time this topic comes up on any media site, I always feel like people who are advocating for accepting many genders are just attention whoring. They take some tiny detail of who they are, and make themselves all about this tiny thing, saying that they are another gender because of it. I'm totally ok with transgender people, since their problems and woes actually feel real to me. Sorry if this paragraph was incoherent.
