I read that as "different because..." implied the author was in the closet.

Also, I live in a UK city that may be in the top three for left wing, LGBT, etc support and my best friend has had basically all of this said to her because of her sexuality and worse, including threats of rape yelled at her and threats of murder at her partner. I literally never hear these kinds of comments but they are absolutely things people in the queer community hear all the time.

Being a lame ally is better than being hostile though, and it's a shame this comic blends bigotry with well meaning but lame support.
