Yeah. Give it time though - the initial response might not be great. Try to keep your cool as best as possible, don't get bogged down arguing about it, make it clear this shit has to stop or they're going to be seeing considerably less of you. Your dad might act tough at first but if he loves you then it'll sink in. After he's ready to reach out and ask you "why", you just need to keep explaining and showing that you aren't some extremist. Just don't expect that to happen the first time you bring it up.
If you can get them to the point where they're willing to listen, I suggest sharing some good episodes of Joe Rogan, like the one with James Lindsay recently. Long form content like that where it's just two guys talking and explaining how this shit works can be very persuasive.
