Thing is, both are part of a larger state. I'm not supporting Putin's politics, but there is a very clear distinction between internal and foreign conflicts. US civil war and Chechnya secession wars are both of the former type, and in that regard they are very similar, and widespread slavery in Chechnya makes this comparison even more vivid. As for "X good, Y bad", every conflict in history is rooted in different understanding of what's good and what's bad by different groups of people. For Georgia, Abhazian independence bad, for Russia, Dagestan independence bad, as they both claim soverenity over these respective territories. I don't understand why are you talking about it in such grandstanding fashion, it is not some groundbreaking news. So no, you can't equate internal Chechnya wars with international conflicts like Crimea and Georgia. These are two very different conflicts with very different reasons.
