Does protesting on Inauguration Day make a difference other than being heard ?

It helps the Republicans get reelected.

The only thing we heard was breaking glass and the crackling of a limo fire. Nothing about anything they stood for.

So IMO they were just there to be violent. They were likely hired for that purpose for that purpose alone and likely by a Soros funded group.

Sure: it makes libtards look like sore losers. Ditto for the boycotters.

Protesting because of some b.s feminazi cause.

They needed attention. You know. Like children who don't get their way,

Would you listen to somebody if they were screaming in your face, threatening your family, destroying businesses, violating every right they proclaim to stand for and physically abusing innocent people?

It is called expressing the first amendment rights

Yes. It increases insurance premiums. Smashed windows and all.

It further alienates the middle-class. If they continue, and Congress Dems. are obstructions, Dems will lose even more seats in 2018. They're cutting their own throat.
