Hi! do you think that hatred is a right?

Hi! i am a south korean. I am currently studying at sogang university, which is located in seoul, south korea. today, i was looking my university community site and found alot of hate speech posts towards lgbt by other anonymous students. i tried to refute their opinions. but they were so insistent.the posting is lasting for more than 6hrs. so i got exhausted. well....i just want to tell you guys about their opinions. they said thatgays are the spreading center of AIDS since the anal sex is anormal. anal sex is so dangerous, unhealthy.Homophobia also has right to hate someone. it is right to articulate one's own opinion in democaracy. reversely, having someone to stop articulate his or her opinion or preferences is a violence.Hatred and aggression are human instincts for survival. so just let it be. straight males have intrinsic irreparable homophobic traits for their own survival.GAYs are promiscuous and sleazy. that is why gays get more STDs than heterosexuals. so gays should be quarantined or should not be openly talk or express their own sexuality5.what if you do if your siblings, relatives and friends are gay? would you still support homosexuality? you can say you support homosexuality because you don't have any homosexuals in your vicinity.well there were more than i wrote here. i just could not translate every hate speeches i've read. these busted opinions don't make sense at all to me. but some students don't even afraid to articulate their hate speeches. cause it's right to articulate their own preference and hatred. it's the right of expression. i feel so depressed. i hope that i can leave these morons and these homophobic country behind someday. i am having been gone through these scumbags for my entire life. i was trying to talk to them, providing them with some academic recourses such as judith butler. but maybe i was not persuasive and eloquent enough to stop their hatred. do you think any of those make sense or are valid?
