Are we supposed to be accepting the thoughts and not interacting with them or accepting the thoughts and agreeing with them?

I see a lot of posts and comments here along the lines of... "the thoughts/urges aren't you -- they're just OCD." Though this is often true and comforting, isn't this just a form of reassurance? The way to beat OCD is by accepting that the distressing thoughts MAY be true/real, a.k.a. "from you" or "not just OCD." By brushing distressing things off as "just OCD," you excuse the thoughts and therefore feel reassured. Obviously it is good to be aware of what OCD does to you and know when you're experiencing a spiral, but crediting all distressing thoughts to OCD is a way of finding certainty about them. What do you guys think of this? Am I right or wrong? This is just the way I think about it, but I see the "this is just OCD" thing so much on here and I often wonder if that is a form of reassurance.

I've been told a lot that in order to get better, we need to tolerate uncertainty, which yea I get that and I'm trying every day more and more to reach that point!! But I've also been told that we need to tolerate uncertainty AND "our worst fears becoming true". Like how does that work, especially with POCD, OCD about a///ault, SA and all of that? Like that is really difficult for me and I don't really understand how I'm supposed to just shrug stuff like that off

I heard that you let the intrusive thoughts be there and don't perform the compulsion for ERP. I'm stuck on the "let the intrusive thought be there" phrase. Does this just mean let the THOUGHT be there, or does it mean to make the contents of the thought to be there and become real?
