It just is.
No black person should be "proud" of being black. It isn't an achievement or an accomplishment. No white person should be "proud" or being white. That too is neither an achievement nor an accomplishment. Should you feel ashamed of being black or white? No, of course not. But being proud of something you had nothing to do with is illogical.
Because I believe genetics play a large part in sexuality, I feel the same way about homosexuality. It isn't something to be proud of. Again, it's not an achievement. Being gay isn't inherently better (or, in my opinion, worse) then being straight. It just is. You were born that way.
Don't be proud that you're a woman. What is there to be proud of? Genes mixed in a certain way. What an accomplishment. You worked hard to make that happen, right?
(Don't take credit for the work your chromosomes did)
The problem is, when people take "pride" in things that are entirely out of there control they center their identity around it. Naturally, because their entire identity is built around these factors, they are very sensitive to criticism.
Take for instance, black lives matter. (Yes, I'm going there). Most people understand there's a difference between me criticizing black lives matter the movement and me criticizing the idea that black lives matter. But, somebody who is "proud" of their race isn't always able to distinguish the two. Black lives Matter is a movement started by black people, so in their mind my criticism of the movement is a criticism of black people (which is true- I'm criticizing certain black people. But not because they are black) and, by extension, a criticism of them as a person.
And what about gay pride parades?
At gay pride parades, gay people aren't talking about how great it is to be gay. They're celebrating and dancing and having fun and listening to music. Only a stiff would have an issue with that. I have absolutely no problem with gay people celebrating- that's only natural, after years of being treated differently. But why gay "pride." Why not gay "victory" parade or just a parade to celebrate a ruling. Even if people oppose your way of life having it isn't an accomplishment- and if it is, you are basically saying you choose to be gay.
This was a short, quick, off-the-cuff MyTake. The next one will have a lot more. That said, I hope you enjoyed.
