No.
Antifa may be misguided in its approach to fighting racists and fascists, but... it's fighting racists and fascists. This is and will always be superior to Spencer's views. What's worse: "alt-right" people getting punched or maced at a protest, or those same people wanting to evict non-white people from where they live, harass them and (in extreme cases) attack them without provocation?
I have a personal stake in this, too. My brother's wife is black. When you say Antifa is worse, you're telling me that my sister-in-law's freedom and safety are less important than that of white nationalists who barely tolerate her existence (and let's not kid ourselves: some of Spencer's supporters don't even tolerate that). Condemn Antifa when it resorts to non-defensive violence, by all means, but the greater problems are unquestionably the racist and fascist ideologies they're opposing. Antifa is advocating for small-scale violence; Spencer is ultimately advocating for violence against millions of people (through forced deportation and other racist laws), even if he sugarcoats it by dropping words like "peaceful" in front of horrific concepts.
