I'm not really sure I follow your last sentence. No one here believes Trump's BS. The objective reality is that the election is very close and will be decided by thin margins. At best, that means we're about to go through two more months of "stop the steal" BS, and conspiracy theories, and lawsuits, and who knows what else. Being concerned about Trump winning the election, which is a very real possibility, and/or about what will happen if we don't know an official result for days, which is also a very real possibility, does not correlate at all with believing Trump's BS.
I guess my complete response would be, how are you NOT freaking out? How is, like, a 40-50% possibility of a Trump win (likely coming along with control of both the House and the Senate) not raising a huge knot of stress in the pit of your stomach? I sure as hell hope it doesn't happen. There's still a good chance it doesn't happen. But I find it hard to understand an "everything is good" mentality at this point. Many of us had that mentality in October 2016, when Clinton was blowing Trump out and we were laughing at Pubs all the way to the finish line. After that debacle, how anyone could ever again go into a Trump election - knowing the stakes and consequences if he does win - with calmness and confidence is beyond me.
