I was looking at a group chat that anti-porn

Hi im a teen, and I’ve loved to look at what people think but I saw on an anti-porn group on Reddit Is that they have demonised porn as a whole, I know that you know that we all have watch or looked at it atleast once does that make us bad people? And a post saying “is watching porn cheating” it said a lot of people said no in the screenshot, if I would want to add on to it there are times and places for these things watching porn with your partner make it fine or is it like going on a double date? But anyway what do you think, is porn bad as a whole and why?
