I don’t have any living ones, but at least on my mom’s side they seem to have been pretty nice people. Can’t say much about my grandpa in his elderly age since he died when I was fairly young, but my grandma was sweet, whether she was just at home or out and about.
Can’t say much for my grandpa on my dad’s side since I don’t remember him, but from what I’ve heard from stories from my parents, he may not have been the nicest person in general. Definitely glad I didn’t grow up with him because I remember a story my dad told of him breaking a dish at his house and then hiding in a closet, not knowing how he’d react to the broken dish or something like that. Something like that. Thankfully my dad is absolutely nothing like how his dad sounded. And my grandma on his side didn’t seem much better, considering when my mom was pregnant with my oldest brother she tried to get my dad to ditch her.
Edit:
I’ve been told before that my mom absolutely wouldn’t let me or my older brothers be alone with my grandpa on my dad’s side.
Edit Edit:
As for tolerant, I can’t speak for any of them that much, but I at least know my grandpa on my dad’s side had to have some degree of tolerance considering he was gay and at one point had a partner. I assume being married to my grandma was more of one of those societal pressures back then. Just getting married in general, even if it ends in a divorce like their marriage did.
