It is sometimes said that reality has a liberal bias. But it is literally the case that historians rank these two presidents at nearly opposite ends of the spectrum, and the article's tone seems to reflect that. Which isn't really an example of bias in Wikipedia - it is supposed to reflect what reliable sources say.

OP’s chosen example was terrible. I’d agree with the premise, based anecdotoly but what a terrible selection of articles to prove a point. Better to link the discussion articles where the editors actively slant the articles

People become more conservative as they age, so maybe the reality quote is about the young and the young edit Wikipedia more

I think people become more conservative as they get wealthier. Getting older just correlates with increasing wealth.

I think it's more about the way things are vs the way things "should" be.

e.g "teens are going to experiment with sex, so comprehensive sex education is the best way to keep them safe"

vs

"Teens should not have sex, so abstinence-only education is the best way to keep them safe"

"The purpose of a system is what it does". Dangerous principle to apply too literally but almost always worth considering. In this case, the purpose of abstinence-only education is to increase teenage births and the purpose of modern sex education is to decrease it.
