One man's "strawmen" are another man's real issues. If you disagree with someone on what the problems are, all he says would look like strawmen.
That doesn't warrant a "douchebag" stamp.
Plus I don't think the word "douchebag" or "douchey" os appropriate for a discussion among people that are not 17-year olds, 20-yo tops. There are far better adult swear words available if needs be.
So yes, I consider it douchey to open a completely pointless debate where there could have been a constructive discussion about the strengths of CL.
