When you have one party making election denialism a core of their belief system while on the other side you have a few random people making claims on social media, it is absurd to claim that “both sides … seem to be doing it right now”.

But that’s both sides doing it. You just described people from both sides doing it…

No, both sides have not made denialism central to their party platform. No, the Democrats did not have any cabinet nominees who refused to acknowledge the legitimacy of the last election. No, both sides did not storm the Capitol building in an attempt to prevent the certification of the election.

Right, and I never claimed so.

No, both sides are not doing it.

I’m sorry but they are. What you have a problem is understanding the difference (not even nuance) of “both sides are doing it” and “both sides are doing it to the same degree/same level/whatever”. It’s two very different things.
