I don't care about gay pride
How do you define 'gay pride'?
It's the idea that they are better than heterosexuals.
The LGBTQ community has faced a lot of discrimination throughout history and pride isn't them thinking they're better than heterosexuals, it's them be proud of who they are. You should be supportive of the movement.
Why? No one has ever hurt me because of my sexual orientation.
The LGBTQ community has faced a lot of discrimination as a minority group and it's understandable that your experience based on your sexuality has been different. You should support gay pride as a sign of support and let them know you care.
