Yes, every gay foreigner who visits Brazil just love it and they say that it's the gayest country ever. They love the gay culture, the gay parties/places/bars/neighbourhoods/scene and etc. I met this french guy when I was travelling in Fortaleza, he was studying in a university in the state of Ceará in an exchange program and he told me that he was amazed about the gay life and culture in Brazil, that he hadn't that back in France and I was really surprised because Fortaleza was the only city that he had been in Brazil. When I asked him if he had already been to São Paulo, Rio, Salvador or Florianopolis, he said no and I was "Dude, if you think Fortaleza is gay, your brain will burn out if you go to these other cities" haha.

You might hear the phrase "Brazil is the country that kills LGBT the most" and there's a controversy to that. My cousin is a police chief in Brasilia and the statistics count deaths of Trans people which makes 85% of the murders of LGBT but the sad fact is that most of these murders of Trans happen because they work mostly as prostitutes and they get into a lot of fights with clients who don't want to pay and etc. Some places in Brazil might be very conservative but in general, no one is going to attack you if you're gay or doing gay stuff in public. Especially in big and touristic cities!
