I believe legalizing marriage, normalizing LGBTQ couples' status first to prove the general society that they're not actually some sick perverted sickos before we allow children adoption, should be the first step. Also waiting for the old people to die out, to put it bluntly.
Keep in mind Poland is still a hugely conservative society, in full grasp of the Catholic church. It's changing, you can clearly see the trend, but on the other hand our current government is still actively painting LGBTQ+ as some sort of harmful ideology or what not. We have a long way to come.
I am against a law allowing LGBTQ couples to adopt children in my country (Poland). I am not in any way against it as a general idea, but Polish society is full of full-on bigots and these kids would be subject to so much bullying, it's really against their best interest.
The argument a lot of people raise "if we start doing it then people will get used to it" doesn't work for me, because why should these children be victims of war that is not even theirs to fight? The whole thing makes me sick.
I've been downvoted for this opinion by both sides on Reddit.
