Uncertain times. Good thing I have a habit of downloading everything I like, hah. Safer this way. Already some games disappeared from itch, but I have them. Perks of living in a kind of 3rd world country where I can be cut off the Internet any day potentially indefinitely. I'm mentally prepared for this.
Revising certain parts of the game feels like letting them win, but you should do what you feel is right and safe for you in this situation. Still, I think a separate nsfw patch is a good idea, if you'll be forced to do that. I think now is a good time for us to download games which could be under the threat of being deleted. But let's not panic. Let's be strong. Community should rally, because these activists will not stop here. There's a visible, massive reaction from the society, like petitions, and also there's a bill H.R.987 - Fair Access to Banking Act (which is similar to the ACLU petition?), if you're living in the US (I'm not, so this info is for others). Things may change for the better in the days to come. Even if not, there are already ways (and I'm sure there will be more) to ensure indie games with lgbtq+ and/or nsfw content will continue to be distributed. Self-hosting sites, alternative payment options, etc. Yes, it will be harder, but possible.
Sorry for the mistakes/messy writing, English is not my first language. Wish everyone the best in these times.
