First I'd like to say that the statement repeated endlessly on the internet that "every day is Straight Pride Day" is flatly inaccurate. Maybe Parents' Day is (but I suspect many pro-gay people would object to that). Children's Day isn't Straight Pride Day. Independence Day isn't Straight Pride Day. Christmas can't be called Straight Pride Day (the Virgin Birth doesn't count). and given that the defense of "every day is Straight Pride Day" involved straight privilege, perhaps "every day is Straight Privilege Day" would be a more accurate statement. Every day might be full of straight privilege without every day celebrating straight pride, and the arguments I've heard fail to make that distinction.
That's fair enough and I'll concede the point. I don't see a huge difference between straight pride and straight privilege myself, but I suppose ymmv there.
Also, even on the assumption that every day is Straight Pride Day, this cannot mean that every parade is a straight pride parade.
No, although I'm sure that normal parades continue to show (for a lack of a better term) heterosexual-friendly content vs. things that would be more inclusive to those which fall outside of the binary. Which isn't wrong at all, but also shows that there's no necessity for a "straight pride" parade.
Additionally, people indicated a gay pride parade is a matter of life or death seriousness. Some people even indicated that the whole point of a gay pride parade (and hence, what is wrong with a straight pride parade) is the fact that gays have a history of facing discrimination. If this is why nobody addressed my question of "don't homosexuals say everyone should be proud of their sexuality?" then the parade needs a new name. Call it "gay equality parade." For that matter, why don't they just march? Even leaving aside the issue of how a gay pride parade looks, this would be an appropriate step toward treating it as a serious civil rights issue (as the civil rights marches black people did in the Civil Rights Movement). As it stands, the need to have a gay pride parade suggests some have an excessive interest in celebrating, are not taking it that seriously until someone else wants one, and actually do oppose straight people being proud; all of which makes the debate about the Brazilian straight pride parade an unquestionable example of gay privilege.
Regarding this I think valoo put it pretty well, but I'd warn you that the term "gay privilege" isn't doing your argument any good. Having a parade that is meant to celebrate their diversity isn't really privileged when you look at how they're still facing persecutions in major areas of their life. I also think that the parade itself is already inclusive (I've never been to one myself) when it comes to straight people, so there isn't a necessity for their own.
and as far as TV portrayal of gay people goes, it's not always absolute.
Because according to TV trope analysis, most TV shows just cookie cut characters. Straight, gay, bi, nerd, jock, emo... one type or the other
That would be an entire issue with the media itself, as characters should be round and dynamic rather than being stock characters. Just because the media sticks to its tropes doesn't mean what they're doing isn't wrong in some fashion.
We still have those ethnic days/months because if we removed them, we would be faced down by immense criticism by blacks, Asians, Chinese, Irish, or just general supporters of equality for racism.
Rightful criticism I would add. As you said, it makes people feel fulfilled and validated for what they've been facing.
Also, I agree that this argument is an "lol", lets just say that due to freedom of speech, we can have whatever ****ing parades we want.
Freedom of speech isn't even the point of the debate. The question is about the entire idea behind a straight pride parade and how they can be seen as problematic/offensive. We can use our freedom of speech to debate the issue and we shouldn't have to expect people to walk in and add nothing to the debate while they're trying to look smart.
