Is it ever okay for parents to drop by your place uninvited?

I keep telling my in laws to stop doing this. I’d wake up and find them loitering in my yard. Or they invite themselves over for dinner. Or they’ll get angry I’m not at home when they come over, because I’m not “including them” in my plans. We’ve distanced myself from them and they refuse to honor our request, claiming I’m “controlling and abusive”. Just this week I came home from work late, wife and kids were at sports practice, and my in laws car was right there in my driveway. House was totally dark. I watched from a distance until they left. No text. No call. Didn’t leave anything at my door. Am I wrong for being pissed?

I confronted them about it. They said they were in the area to “watch wildlife” and look at Christmas lights. It was pitch dark and I’m in a mostly rural area. How the fuck do you watch wildlife in the dark? I called bullshit. But they got mad and claimed I was making them feel bad right before for the holidays.
