No. Non sequitur. If I say Pinochet is bad, saying "Allende is bad too" is a completely nonsensical comparison, as they aren't even remotely similar and the things people are claiming are bad aren't even in the same categories.

It would be like someone saying "Kim Jong Un is a horrific leader" and then another person responding with "yeah well my home owner's association president is terrible too." Just a complete non sequitur.
