You just classified a statement that includes "probably" as absolutist. Perhaps you should reexamine it and consider whether your own context is causing you to interpret it slightly differently than intended.
And yet I don't think it's clearly inflammatory. Again, perhaps what you are interpreting as clearly inflammatory was meant to express something other than that.
Of course, this could all be cleared up if you actually explained what you thought was so horrible about the original comment. So far you've called it "absolutist" and "clearly inflammatory" but not actually explained why you think so. Obviously, at least one person disagrees, so perhaps backing up your statements with your reasoning would help.
I'm cool with it being considered inflammatory to oversensitive Californians. Their reaction is exactly why people in the other 49 states don't like California. You can't remotely criticize CA at all, it's a wonderful magical land where everything and every person is better than everywhere else. They'll take offense even when they don't meet the profile that the criticism was intended for, just because it might offend someone else in CA.
