Being heterosexual is a privilege since it's the norm, so you don't have to worry about it. Being gay on the other hand can be dangerous, even life threatening depending on the country.
You're projecting on to me right now.

But based on your answer you are also making a delineation between "blogspam" and for example someone posting a story about discrimination for being gay (for example).
But, for someone who is gay, by mearly showing a picture of themselves with their husband they'd be "declaring their sexuality", and being "overt"; They don't have to say anything more. Their _existence_ is politicized, and that's the problem.
And when we say "don't show rainbows", or don't show anything that can be linked to LGBTQIA, we're really saying,
"You can't do these otherwise non-political things, because just being who you are is still politically charged". We're better than that HN.
Also, a photo of yourself during your wedding is not a "weird home life". That's like the maximally normal home life thing. I think it would be flagrantly out of bounds for someone to tell a co-worker that their wedding photo is "weird home life" stuff and to keep it at home.
Edited to add: I don't really have anything against the advice of not putting your personal life at work. i.e. photos of kids, spouse, vacation pictures on linkedin, etc. I'm just confused why apparently only gay people can't do it according to OP. That's so bizarre to me.
This has nothing to do with your individual sexuality. Everyone looks ridiculous being overtly personal on LinkedIn.
