This is actually a behavioral pattern of the masses, and it's very frequent in comedy.

When somebody publicly pokes fun at a group, very often, advocates of the group (who do not belong to the group), will complain, even if nobody belonging to the group actually complained.

I remember a comedian telling how he made a joke about priests, and while a priest actually wrote it was fun, religious associations (not priests!!) went berserk.

Such cases are ego trips, however, I can see how it's difficult to handle them in a politically correct manner (I'd tell them to shut the mouth, but it's not possible in real world).

Christian is a normal and very common German first name. That alone doesn't tell you anything.

Santa hats are a very normal sight in December in the United States. That alone doesn't tell you anything.

Are you wearing one right now?

I am, actually. It’s cheap and itchy.

Nobody offended enough by a santa hat to open a bug report would use the name Christian on that bug report. Obvious troll.

Come on, this is equally ignorant on your part. First names are decided upon by the parents and that's it. In a lot of places, you're stuck with that for life. Inferring trolling from a user name that is a plausible real name is just ridiculous.

I am not defending the bug report itself.

They would've used a different name on their github....
