American insurgents? Gonna' be tough to stop them or slow them down, without infringing upon our own valued freedoms and rights. Interesting parallels between ANTIF and Islamic extremists... Although ANTIFA is likely a minority within the left, there is some degree of sympathies within the party, and a distinct lack of condemnation for their actions. The best way of at least slowing them down would be open and ardent condemnation from the left, including the media. In the meantime, the moderate left see a growing "alt-right" movement, and are becoming more sympathetic to the "extreme left," and the moderate right sees what groups such as ANTIFA are doing, and are becoming more sympathetic with the "alt-right."
