Uncalled for. Try to follow the guidelines instead of calling people names.

Speaking authoritatively about subjects with which one is unfamiliar is likely to have one’s speech recognized as ignorant and confused. This is not uncalled for, particularly when coupled with a substantive explanation as to why.

What about the guidelines for downvotes?

If factual comments are downvoted without consequences, then the site becomes nothing but a place for reinforcement of social fads.
