I seen this coming...
Am no Trumpeteer. My distaste for Trump is known on this forum. But the bottom line is that the root cause for this came from the Left when the Left's political leadership allowed, meaning they said nothing, the riots by BLM, ANTIFA, and assorted opportunist anarchist groups. The Right saw those riots as tacit permission to resort to violence to gain political goals. Trump does not help with his social media blathering, but he did not caused this.
Ultimately, this will blow over. Historically, the Left have always been the most vocal when it comes to political goals, but now everyone seen the Right can do the same and perhaps even more intense. The Democrats should pay heed. The House is barely under Democrat control. When all calmed down, two yrs from now, I predict that the House will be under Republican control and Biden will not run for reelection in '24. There will be a 'new' Right in the sense that conservatives and conservative leaning centrists will be more politically active at all levels.
