Except he didn't equate the two as a whole. He compared one aspect of the two to illustrate a separate point (zealotry). Said differently:
An apple is red.
A Nazi flag is red.
If somebody says he likes apples, is he also an antisemite?
I will try and explain this in incredibly simple terms in the hope that you understand it.
Someone who has never experienced racism describing being slightly annoyed by something as "like racism" is trivialising a serious issue.
Racism is a thing that is real. People have lost their jobs over it. People have lost their lives over it. It is
not trivial.
It has no bearing - literally
none - on "reasons group x does not want a PS4Pro".
If he wanted to use the word "zealotry", well, why didn't he fucking use that word? Or elitism? Or arrogance? Or prejudice? Or closed minded? Or the dozens of words that can be used as a pejorative adjective to buffer what is essentially a rather weak point?
e:
I'm not going to go all "check your privilege", but someone who has never encountered racism
really fucking shouldn't equate it to minor annoyances
