There are myriad number of reasons why I think Bruce is wise to be wary. I would feel completely unwelcome in Poland. The most recent is the appearance of "LBGT-free" zones which are really quite extensive. I'm not putting someone I love in such a hostile environment. That's just to start.
According to a recent survey, Poland has the largest gap between life satisfaction of LGBTI people and the general population. Let me know if you would like to see the details of the results. That doesn't bode well for gay travelers who may inadvertently trigger incidents due to cultural differences or unawareness of local norms and expectations.
Many of us travel for reasons other than visiting the gay bars in the largest cities. We all know those are most often safe zones. We don't want to spend our travel time in clubs. Some of us have progressed past any need for club life and really aren't looking to participate in parades or protests. Feeling at ease in exploring a country and being allowed open expression is enough for me and my spouse.
Poland in general is one of the most openly disapproving environments for LGBTQ+ people and mainly due to the prevailing religion. I'm sorry but it has become off limits to us because of the developments over the past several years.
