I can’t really think of a reason for that as Reddit is hated somewhat equally by “both” sides of the spectrum. It’s just something I find interesting.
The problem with using the term “the left” (much like any board term) is that is definition is nebulous. Political leaning is relative to the reference ideals.
The point I’m getting at is that it’s imaterial to your issue, with this one person and while you have your right to be upset with them it’s a bad basis for an argument against a group especially one so ill defined.
I would argue that, in an informal and somewhat overvgeneralised sense, people do trend to the left and right sides. A person who hates abortion is more likely to be for gun rights, for example.
And in my experience, the people who use the term dog whistle tends to trend towards the left socially.
