You realize non-liberals and even -- gasp -- Republicans work at Meta/Instagram, right?
The assuming and derisive comment with baseless and needless attempts to start political mud-dragging shows the only one with a "sense of self-righteousness" here is you.
If you're going to try and make claims like that, either cite sources, or stop making things up to try and push your own (in this case, "liberal"-bashing) agenda.
In short, do better.

Stop pretending that conservatives are victims on social media, they're not -- you're just desperate to be oppressed.
