I don’t talk the serious but inconsequential issues like politics, religion, or other social debates with really anyone IRL.
There are a few in my life that would like to troll me into arguing with them, but it is not to be done as an equitable exchange of idea, but rather an attempt at bullying someone who thinks differently than the majority. So, I do not discuss controversial things with many acquaintances, it wouldn’t accomplish anything at all.
I have some friends with whom I can discuss such matters, but we are less in disagreement. A discussion about healthcare there would be disagreements about the best methods of ensuring that everyone gets covered, but not debating whether or not that should be the goal.
So, coming here allows one to debate in a lower stakes environment. I have no family to disown, friends to lose, or clients to alienate.
In that context, yes, arguing is fine, even if it is futile (and if you think that debating on here with non-trolls is any less futile than arguing with trolls…), if you enjoy it.
And well, even with trolls, there is often something to be gained in enjoyment from at least the first couple of rounds with them.
Though, yes, they do get tedious after a time, and are less worthwhile to engage, but to some extent it ends up being a matter of trolling the troller. You get the same whatever it is that the troll gets out of trolling, but without the guilt or disruption of trolling someone who actually has useful things to say.
