I'm afraid I don't know what you mean. What is an "evo"? Do they hold local chapter meetings?
Posters from both sides of the debate have argued from association.
Things heated up last summer with a number of longtime FReepers--one person had a homepage disappear on them with no immediate explanation forthcoming; there was another thread in which one user posted real-life name and other information of another FReeper with whom he disagreed (both ended up banned or suspended--and I only heard of this secondhand, as I was in Alaska when it happened); and things generally got worse for all concerned, until an infamous thread in which the crud generally hit the fan.
Many of the pro-evo folks--but not all--quit or were banned at that point; a large contingent of them went over to another site called Darwin Central.
Quite a shame that things fell out in the fashion that they did : many of the now departed were PhD level and very intelligent and informed on a wide variety of topics.
(If you know where to look, there are still a goodly number of other folks of equal IQ and/or education left on FR: they just don't tend to congregate in crevo threads anymore.)
But I still wish things had been resolved more amicably.
