You need a timeout.
Attacking Putin lovers is the patriotic thing to do. They post Russian propaganda here daily. More serious things should be done besides you getting offended.
From the classical Kantian perspective, we only have direct moral obligations to persons, defined as rational people with self control. A Putinist is not a person, and therefore, we need not worry about being nice to them. It is like being nice to a rock, or to rats. From a Utilitarian perspective, anyone who can experience pain or pleasure has some kind of moral standing. Putinists, however, only experience degraded pleasures, like the pleasure from treachery or lying. No matter how I approach it, I can’t think of a good reason to be very nice to them.
