Charlottesville was a fight between two groups The alt-right was very small. On YouTube I saw two women being taken away in handcuffs, so the problems were on the left as well.
The situation of the driver intentionally driving into those people is highly suspect. Please research.
As for politics, the alt-right is concerned about Jews. Of course there is no valid reason to be prejudiced against regular people.
However, Israel does have too much influence in our government.
Consider that Israel has not treated Palestinians well for decades. The BDS movement wants economic boycotts against Israel.
Almost the entire US Congress (except a few representatives) support the Israel Anti Boycott Act.
This is probably going too far, but the left is very angry and intolerant, and definitely does not support freedom of speech any more.
That alt-right group protesting in Charlottesville was a small number of people. What do you think would have happened if the left had not expressed their anger and ignored the alt-right protest?
