I read your argument to be that the terrorism is justified in one case and not justified in the other. That may be the case, but many will disagree about which form of terrorism is justified and then you have a bunch of terrorists everywhere.
My argument is that neither terrorism is justified, and both were enflamed by the state of politics and most of the violence/bad behavior was done by desperate criminals or the mentally ill.
You yourself said people were rioting for political purposes. Either rioting for political purposes is terrorism or it isn't, regardless I hope you apply whatever standard you use uniformly and recognize that the riots and Wednesday were both caused by divisive political rhetoric causing ideologically motivated people to think violence is their best option. Introspection is important as is empathy for those you disagree with.
