I lean conservative, but to be honest, I assign only a small portion of the blame to social media giants. Their office areas and leadership certainly lean left-wing, but I don't think that's the main issue.

As a result, even an entirely neutral algorithm focused on retention / user satisfaction will…
Considering "right leaning views" includes things like women should not have reproductive control over their bodies, trans people should not be able to use the bathroom they feel comfortable with, and gay people shouldn't be married, and people should have their children yanked away from them at the border, yes, I can very much see why they would be offended by that.
You're not getting a lot of people being offended by the nuances of tax policy, for instance.
