Your claim is that it is all right wing people becoming anti-social in unrelated areas?
Nevertheless the pandemic responses by various governments I have to interact with have done much to deepen my distrust of them and the society around me.
Various governments have deployed drastic measures such as lockdowns in an effort to control the pandemic, but they’ve released little evidence to demonstrate the usefulness of these measures.
Research is increasingly showing that the lockdowns were not worth it. If that is really true their victims should be lavishly compensated and those responsible actually held responsible.

Of course I personally am not qualified to judge whether or not the lockdowns were a mistake, but the evidence seems to be piling up against them. The governments could alleviate these concerns by showing solid research confirming that they didn’t fuck up.
The "feel that they’ve been unfairly imprisoned in their homes by the rest of society" was very right wing attitude. Even in places with no lockdowns and no restrictions. Even left wing disagreeing with this or that measured would talk about these in less emotional terms.
Also, coincidentaly, similar division occurred across Europe. The people more likely to be influenced by American conservative thinkers were more likely to be hostile to masks and lockdowns.
Honestly, how is any of that controversial?
OP could have stated it in more neutral terms, but chosen not to.
