I guess it's like a marketing funnel analysis. In one case, you could blast advertisements for your product but end up with a ton of bad press (lots of impressions but an increased public stigma against what you're selling) and in the other you can rely on organic traffic but have a better ability to tailor your audience's perception of what you're selling.
I'm not entirely certain what would result in the most throughput but I err on the side of explicit exchanging of ideas, I suppose.
Also, the supposed "violence" from the counter protesters is being incredibly way overblown. The Nazis murdered someone, injured many others, and beat a black man to a pulp in a parking garage. Not too worried about a few punches thrown at them and some mace sprayed their way.
Some serious perspective among folks on the right seems warranted.

That's the difference between you and I in regards to this situation. I reject all violence and you excuse some violence based on politics.
