1.) Snopes claims this but repeated requests to the City of Charlottesville to produce said permit have been ignored. Which is odd. 

2.) I don't know if she was attacking anyone. Her murder has absolutely nothing to do with the topic of discussion (freedom to assemble and freedom of speech). It's perplexing that you'd mention it in a rebuttal.

3.) The city approved the permit, then tried to rescind it, and a judge forced them to comply with their own permit approval. When counterprotesters became increasingly violent, police forced the racists to leave the park then failed to escort them out, allowing the violence to continue. This is government persecution on several levels.

4.) If you can't be bothered to sit and watch video of the incident I don't know what to tell you. They showed up in full battle rattle like Antifa always does. They threw urine, bottles and rocks at the racists and the police. YouTube: it's free. Tons of unedited video of this.
