this is poorly expressed, but i think you're trying to say that privacy can only be justified to hide 'unwanted' things, and so arguing that people need privacy to hide being gay implicitly accepts that it is bad to be gay
this is the premise i explicitly rejected in my comment; to use that example, this is an instance of what i said
gay people need privacy not because being gay is bad
gay people need privacy because others' intentions and judgment toward gay people are bad
you seem to be arguing that it would be good to improve others' intentions and judgment toward gay people, and this is correct, but there are limits to how much mere exposure can effect such a change
i am not willing to sacrifice gay people's lives for that
it should be extremely obvious that your reasoning is invalid in some of my examples
your teenaged neighbor doesn't want everyone to see her in the shower and to know when she's alone and unprotected because she's vulnerable to being raped
there is no assumption that the shape of her breasts or her walking home alone last thursday are 'something different and unwanted' or in any way bad; quite the contrary, her ability to walk home alone is precisely the good that it is important to protect in this situation
the problem is, as ought to be obvious, certain other people's intentions toward her; she needs privacy to protect herself
I understand what you're saying but my point is if we didn't try to protect X, it would eventually be normalized, become part of daily life and not noticeable as a thing that needs to be protected AND that it seems that when putting protections for X, that protection implicitly includes the assumption that X is bad. A naked body isn't inherently an invitation for rape, unless you implant that idea into someone's mind through the ban of public nakedness, and being gay isn't a thing to judge, unless you make it a taboo and discourage its public expression.
I'm not convinced, the real life evidence in actual tolerant societies seem to suggest that the more open we are, the less secrets we keep and the more transparent we are, life improves.
people need privacy because others' intentions and judgment are unworthy
if you've ever known anyone who was gay, who got divorced, who secretly had a deprecated ethnic background, who left their faith, who didn't want their ex-boyfriend to know where they lived, who revealed government corruption, who struggled for political change, or who could be raped or robbed by a stranger, you've known someone who needed privacy
even though they had nothing to be ashamed of
you might argue that if nobody had privacy, nobody would be able to get away with rape, or with lynching people they discovered had a drop of black blood, or with lynching apostates, or with gay-bashing, so these things wouldn't happen in a world without privacy
that would be a stupid argument because people did those things openly all the time, and they usually got away with it, and some of them still do; humans have a social pecking order, and it is defined by aggression with impunity
also people murder their ex-partners all the time even when they won't get away with
