It’s more likely that you became more radicalized so what used to read as neutral seems partisan now.
I mean... this is a very real phenomenon, but probably not in the way you're thinking of.
There are many simple statements of fact that, 15 or 20 years ago, were as universally uncontroversial as "the sky is blue", but today are considered radically controversial political opinions, and will get you banned for most online platforms if you dare utter them.

Is it radicalised to want even a basic premise of neutrality in an encyclopedia?
Despite not being particularly political, even I raise an eyebrow when an article opens with "____ is a <negative label>, <negative label>, <negative label> known for <controversial statement>"
