One helpful response - not for Hector but for others who are sympathetic to anti-fascist motives - is to note that if you go to the Rose City website, you won't see any evidence of anything even hinting at violence.

So actually, without realizing it, Hector gave us a link which proves he is wrong.

Here is a review by a legitimate organization that notes that over nearly 3 decades, 335 deaths can be attributed to right wing terrorism, and 25 to left wing terrorism (note that Antifa wasn't mentioned at all)

Based on a CSIS data set of 893 terrorist incidents in the United States between January 1994 and May 2020, attacks from left-wing perpetrators like Antifa made up a tiny percentage of overall terrorist attacks and casualties. Right-wing terrorists perpetrated the majority—57 percent—of all attacks and plots during this period, particularly those who were white supremacists, anti-government extremists, and involuntary celibates (or incels). In comparison, left-wing extremists orchestrated 25 percent of the incidents during this period, followed by 15 percent from religious terrorists, 3 percent from ethno-nationalists, and 0.7 percent from terrorists with other motives. In analyzing fatalities from terrorist attacks, religious terrorism has killed the largest number of individuals—3,086 people—primarily due to the attacks on September 11, 2001, which caused 2,977 deaths. In comparison, right-wing terrorist attacks caused 335 fatalities, left-wing attacks caused 22 deaths, and ethno-nationalist terrorists caused 5 deaths.
