false equivalence 

When used on Reddit or other social media, a claim of false equivalence is not, as one might expect, pointing to a fallacy of inconsistency. Instead, the term is indignant shorthand indicating that the respondent is offended that someone had the audacity to make a comparison that illustrated how ridiculous, unreasonable, and/or stupid the thing they said really was.

Comparing Hitler to Stalin is a false equivalence.

False equivalence 

Used when a liberal has absolutely no comeback for your undeniable facts and comparisons. Employed when they have no rebuttal and completely run out of feelings.

Well thats just false equivalence. Explain to me how it is. It just is so your facts are now rendered useless to me
