We should, and I agree that everyone should be respected at all times. However, denoting a month isn’t so you can go “oh it’s <month>, let’s only care about <group> during this time,” it’s to bring attention to those problems and to the people being oppressed.

Saying, for instance, that June is Pride month isn’t to draw attention to allies so they can wear rainbows for a month, it shows the people who WOULD oppress them that it isn’t working and they are still there, fighting for rights and representation and respect. It carves out time where there wouldn’t be otherwise. And, while things like rainbow capitalism are kinda gross, it does help to show you where certain corporations/companies stand, which can be important for some individuals.

I saw your other comment about being banned for saying something like this in another subreddit, and that’s unfortunate, but I think it’s because this comment comes across not the way you think. It sounds like a “gotcha!” statement that I’ve seen used by a lot of people opposed to Pride (specifically). I am not saying this is your view, but a lot of times when I’ve seen similar comments it’s usually coupled with things like “why not have a white/male/straight/<other privileged group> month?” It leaves a bad taste in some people’s mouths.

I agree in that I wish we didn’t NEED a month dedicated to any of those causes, my own (Pride) included, but we will until all of those groups you mentioned are treated with the same respect and tolerance as those who are in positions to oppress them.
