Half of the country believes the election was stolen because Trump and his supporters LIED nonstop for months, without any evidence whatsoever, that it was stolen.  It's unfortunate that he was able to con so many people (including you, apparently) with the Big Lie of election fraud, but it's not Democrats' fault that people believe an election was stolen because they were lied to.

The process:
1. Lie to the people that the election was stolen.
2. When people believe our lies, we'll cry that we have to do something because it's serious business that people think the election was stolen!

Arsonist firefighter. That's not how things are supposed to work in the real world.

Again, no evidence.  60+ court cases, laughed out of court, including by many Trump judges and a 6-3 conservative Supreme Court.  None of the allegations have been supported by actual evidence, no matter how many times you make a broad statement about "evidence."  (Trump and Rudy claiming it doesn't count.)

Here is what the Republican led Senate Intelligence Committee had to say about the Russia collusion charges:
"The Committee's bipartisan Report unambiguously shows that members of the Trump Campaign cooperated with Russian efforts to get Trump elected. It recounts efforts by Trump and his team to obtain dirt on their opponent from operatives acting on behalf of the Russian government. It reveals the extraordinary lengths by which Trump and his associates actively sought to enable the Russian interference operation by amplifying its electoral impact
and rewarding its perpetrators - even after being warned of its Russian origins."

It's also NOT OK to LIE about a stolen election and fire up a mob for a violent attempted coup because Senate Republicans (above) and Democrats were mean to Trump (poor baby).

Democrats absolutely did NOT encourage BLM violence.  They denounced it over and over and over again - you just apparently have chosen to ignore it.

You're right, I didn't quote the whole speech.  But I did include 902 words from it, compared to the ONE time he used the world "peacefully."  Again, do you think the crowd heard the message of the one time he mentioned the word "peacefully" or the 902 words I excerpted?  Hint: they did the violent thing, not the peaceful one.

No doubt some of the violent mob didn't need Trump's speech to incite them to attack the Capitol and hunt for Mike Pence to hang him - they were already incited by the past 2 months of Trump lying to them about the election being stolen and wanted to get a head start.  Trump's incitement was not limited to the Stop the Steal Rally speech, but that speech represented the culmination of his months-long incitement.
