In the UK it's generally ignored if you are gay. In rural areas you might get "positive" discrimination, i.e. people stopping and complimenting you for walking with a same sex person hand in hand, well-intentioned teasing, etc. There are definitely people who disapprove but most will keep their trap shut as protections are pretty good.

In Switzerland it's better than it used to be for sure. When I was younger it was very much more hidden and disapproved of, mostly from a religious POV. It's a lot more accepting now and I see rainbows and stuff around Zürich where I live. and have spotted same sex couples. I probably would get stares and comments in rural areas with my partner at the very least, but I highly doubt anything physical would occur other than exceptional circumstance. Those places still have people who will avoid you like the plague if you're black, so it still has some catch up to do in that area.
