It’s the one point they always overlook, most commonly pointing to r/conservative bias but they never like it when you point out r/politics is supposed to be unbiased and include politics from all sides. If it was r/Democrat then nobody would have this problem because then they can have all the bias they want.

It would be like r/gaming only posting Xbox related stuff and calling out r/PlayStation for being biased towards PlayStation and never posting Xbox content even though they turned r/gaming into r/Xbox (hypothetically)
