The smart play is when the election is called and it's a Biden victory, stay home. Don't go out to counter protest the Trumptrash. Trump will want to exploit the violence in the streets. That can't happen is no one shows up. Besides if Biden wins, what's to protest?
As to the gun thing, if you're in Portland, Oregon who could you possibly shoot that would have an impact on the transfer of power? What good does it do you? The transfer of power will happen in Washington DC and no amount of violence anywhere else will have an impact on that. So relax, the Police in Washington DC aren't the police in Kenosha. Have an armed, open carry protest here and your brains are will be wall art.
Finally, if I'm the voice of reason, there's a ******* problem here.
