I mean, the sitting president urged his followers to storm the capitol in order to reverse an election result. That's pretty much the most clearcut possible grounds for impeachment that exists.
Can you show me where he directly told anyone to break into the capitol versus attend a protest in the vicinity? There are plenty of politicians who have encouraged people to attend BLM protests that ended up in violence, but for some reason we don’t hold them personally accountable.
Trump stoked the anger and insecurities of his followers and left them to make the final decision about what actions they would take.
You're leaving out that politicians who have encouraged people to attend BLM protests often encourage people to assembly peacefully but to make their voices heard. I haven't seen anywhere prior to the attack on the Capitol building where Trump urged his followers to be peaceful. He has done the opposite, which allowed his followers to infer that he would support acts of violence.
Trump is a master of equivocating - Michael Cohen said so, and if you listen to the hour-long call he made to Raffensperger, you may notice how good he is at saying things...without really saying them. This is super subjective though (which is why it's effective "Oh, no - s/he must have misunderstood me. I would never ask them to do something illegal").
