Inviting bridesmaid's parents

No, that isn't wrong at all. Inviting BM's parents isn't something you have to do anyway. If you aren't close with them, don't feel obligated to invite them.

Nope. I'm only inviting 1 BMs parents. I'm super close to them and have been for over 20 years. I call her parents "Mom and Dad" when I visit versus the other others I barely see or talk to.

No! I invited some and not others

Nope! We invited all of the groomsmen parents and non of the bridesmaids (except for my sister :p). We are just not close with everyone's parents.

I think that's fine! I invited my two MOHs' parents, but both are out of town and did not come.

I'm inviting one BM's parents, only because they're also my aunt and uncle. Definitely not something you have to do!

You should be fine. I'm only inviting the parents of my MOH.

I'm only inviting my MOH's mom.

2 of my BMs parents will be there; for one, my parents are good friends with their parents (known each other since college) and the other I'm very friendly with and have known for 15 years and they also invited my parents to their daughter's (my friend's) wedding.

I am inviting my MOH's parents; they call me their second daughter anyway.

I invited all my BM's parents but that was because I've known them all since I was about 5 and basically grew up with them. I think in your situation, it makes sense to only invite those you are close to.

3/6 BM are cousins so their parents will definitely be there. The other 3 are friends and their parents will also be there. I call all of them my moms/dads, have gone on vacations with them, family Christmases etc. I can't imagine them not being at my wedding. In their own way, they helped raise me by feeding me countless times, giving me a place to sleep, driving us everywhere when we were younger. . .

With all of that being said, if you're not very close, I wouldn't feel obligated.

I'm invited 2 of 7 BM's parents. 4 of my BM's are from college so I'm not very close with their parents and they are out of town. The 2 parents I am inviting are my hometown friends that I've know for 18 years and know their parents very well. The other 2 BM's I did grow up with my but just was never very close with their family and my parents weren't invited to their wedding so easy decision. My FH is only inviting 3 of his GM's parents for the same reasons as me.

All of my BM parents are invited. I have known all of them but one since I was little, there was no way I wasn't inviting them. The BMs whose parents I don't really know, I am still inviting. It'll make things easier for them.
