Those patronising, virtue signalling posters having a go at the OP just need to remember that not everywhere is like where they live.
I have never seen a same sex couple holding hands in my small town or in the 2 neighbouring towns. If I go to Brighton for the dsy, it's completely different. Not everywhere is the same.
In many places, it is still brave for 2 men to hold hands. I have also seen many gay men and lesbians saying that homophobia is getting worse.
I think the forced teaming if sexual orientation with gender identity and fetishism is partly responsible.
Gay rights activists fought for decades for equal rights, to be seen as ordinary people who should be treated as individuals and against the homophobic portrayal of gay men as paedophiles. Now we have Furries at Pride and Drag Queens reading stories to young kids in libraries. Sometimes, gay men and lesbians - through no fault of their own - are getting caught up in the backlash.
Re men holding hands, often by linking pinkies, in India - I have seen this in several countries in Asia, Africa and the Middle East. Sadly, it tends to happen in countries where the homophobia is so deeply ingrained that it wouldn't cross onlookers' minds that 2 male friends could be in a sexual relationship.
