To the OP - generally you aren't going to get people on here to admit to being nonchalant about the virus, so most responses you'll end up seeing will be some flavor of "absolutely not" to "we do, but with x,y,or z precaution". Of course, that's not going to be inclusive of all responses, but there's going to be a bit of an echo chamber.
Me? We see my in-laws regularly. Covid burned through their house a couple months ago, and while they're generally skeptical/blasé about the seriousness of the pandemic they were kind enough to inform us well ahead of time that there was suspected or confirmed cases. We avoided them during those periods, but otherwise my in-laws are in their mid 50's and very healthy.
We also see my parents, but they live out of state. When they come, they stay in our place and don't really leave so essentially self-quarantining. They're also mid-50's and relatively healthy. They're even more skeptical of the nature of the pandemic and early on we decided that for my, my wife's, and ours kids' mental health, we would continue to see both sets of our parents.
I understand this is not a popular approach, that some may be seriously abhorred by our willingness to see our parents, but I'm just laying the cards out in all honesty and won't argue with anyone or try to do mental gymnastics to justify our actions as 'acceptable'.
