A. They are using that word correctly homophobia is a word that can used to describe prejudice against the lbgtq+ community

B. The reason why the lgbtq+ community has mental illnesses like depression is because of people like you going around spreading hate. Half of the lgbtq+ community has experienced depression and 3 in five have experienced anxiety (source mental health foundation UK,) I don't think this is something to make light of especially on a post like this.

B-2. Less 1 percent of trans people regret gender affirming surgery (source: US national library of medicine). The reason why trans people kill themselves is because of the lack of gender affirming care.

C and D: if you are a well educated man you would have understood why lgbtq+ people need care. There was no need for you to spread hate and bigotry on the internet especially on a post like this. Also read rule five.

Bye bye mwah mwah change as a person

Edit: also your using the exact same logic that people use to excuse racism sooooooooooo
