If these things are just social constructs, I don't see how you get to decide which are "valid".
Do we need to quibble over what you think valid means? It's not monolithic either, btw. Social constructs are valid insofar as they apply in terms of what is not some absolute existence, we're always in flux, much as you want things to just stay the same, naive as that is
How? It was created before most were invented. It also doesn't include straight.
Ah, more dishonest characterization of them just being invented, like it was a whim rather than investigation and categorization through said investigation. That'd be like saying Newton just "invented" gravity rather than using it as a term to explain things that had been observed before, but he codified them
and yes, it does include straight in that the goal is reflecting diversity. And even if it didn't, so what? Straight people are meant to be allies, this isn't like a pie, and if one person doesn't get an equal piece it's suddenly unfair. Do you really think straight people are being marginalized? They get the most representation of any sexuality, period, only close behind maybe might be bisexuality, if we're being generous.
It's directly comparable.
It's a dishonest comparison in the same vein as white lives matter. Or do you think that's a genuine counterpoint rather than being outright racist and rooted in privilege where society already treats white people as the norm?
Are you saying that you cannot express pride if you're a part of a majority?
And again, I have to explain that pride in this context is not something the majority needs, rather than a matter of them not being able to. They can express it, it's just patently stupid, because it misses the point and downplays and marginalizes minorities, gaslighting them as if their experience is not more important than theirs (which no one's saying they're more important, because that's not the meaning of pride here, which is more self respect and dignity, not self aggrandization)
: a feeling that you respect yourself and deserve to be respected by other people
: self-respect
2
: a feeling that you are more important or better than other people
3
: a feeling of happiness that you get when you or someone you know does something good, difficult, etc.
Which definition do you think applies to gay pride, to black pride? Because it's not #2, I can promise you that and 1 and 3 are probably the two likely ones, though really, you're still missing the point in that words don't have fixed meanings, they have meaning based on usage, the dictionary changes *gasp* much as you seem to insinuate it's unchanging in the meanings.
