Sadly I think that is the by product of a larger issue where in almost all things in life have become victim to this stance of us vs. them. People pretend to want to have civil conversations around opposing views, but the reality is it's more of a "i'll listen to your view as long as you know your view is wrong" type thing instead of honestly being open to having your mind or principle changed with the right information. The other side effect is everything becomes a political point of contention at some point. It's almost like a new take on Godwin's law where not only is there a probability of Nazi's being referenced.. it's simpler that a conversation will become Democrat vs. Republican. .. Though we know that will eventually lead to comparisons of Nazis at some point too.
I don't see this in real life though, it's only on hyper exposed platforms like the news, websites, social media. In person I find most people are actually still pretty civil (though It's largely based on who you associate with).
Don't debate me on my opinion or else it's obvious you're a shill of "insert something here" ;D
