Opinionated may have ment the 'fight for your view till death' kind of folks perhaps. In which case it is being far from fun.

I've definitely run in to those types at meetups. They're there to ruin the event for everyone (although I'm sure they themselves have a good time).

Thankfully it's possible to convince a smaller group to ignore them (don't feed the trolls etc) so you can have interesting conversations.
