If what you are trying to say is that what's new and modern today will someday, probably sooner then later, be old and "normed" tomorrow, then yes...absolutely this will be the case.

This understanding is the basis of the Right's "slippery slope" argument...that in normalizing behaviors today that yesterday were considered "wrong", they tomorrow can we expect ever more and more outrageous behaviors to follow this same template?

The answer is, of course, yes.

I don't get it, what is that supposed to do?

"Owning the libs", in a way that won't actually change their minds, but will make the speaker feel smarter and righter.

In other words, nothing useful.

It is my belief that many, if not most, people believe themselves to having never changed their opinion, even though they have done so many times. To admit to yourself that you once were wrong is to admit that you were imperfect; it is easier to believe that you have always thought what you currently believe.

And, consequently, if you have never changed opinions, your current understanding of things must therefore be correct and unchanging, and policy can be written and implemented with this assumption.

In a way, it is the antithesis of science.

Sorry, what does "Traditionalist conservatism places a strong emphasis on the notions of custom, convention, and tradition." have to do with the left?

What do you do if they claim to be on the right? Or if they claim that they're not political at all, they're just stating facts? (Genuinely asking!)

For the right, conservatism is their schtick so there's no criticism to be made. One can (and should) disagree with their beliefs but the contents of the box is exactly what the label says it is, so to speak.

It's the new left who claim to be on the side of liberals but whose continue to espouse illiberal beliefs that need to be called out as to what they are.
