Sure, the dangers exist. As do the dangers of being naive to the sides as they exist today, their biases, and the impact the ideas the sides back will have on the life of those who just decide to ignore it all.
And I say that as someone who tries to ignore it all, because there's a lot of nutjobery going on, but quite honestly most of it right now is coming from the leftists.
It is not my impression that those on the right generally think it's all sunshine and rainbows - God, Country and Family are all under attack, Free Speech is under attack, the Governments nowdays don't tend to be fiscally responsible, there are epidemics of decadency, homelessness and drug abuse, and I won't even touch the looming threat of undemocratic world government through the backdoor via globalist transnational institutuions.
I could go on, but hopefully this is enough to illustrate the fact that "the right" doesn't generally think it's all sunshine and rainbows.
As for your final paragraph, yes, placing faith on someone else to solve your problem if only you give them power is generally a bad idea in my view, but most people are not like that, and as much as it pains me to say, this will likely never change.
I disagree that picking a side brings pain and division. It can, but it doesn't have to. It's only when Ego gets in the way (and to the untrained mind, which is mostly everyone, it often does).
Ideology is a tainted word, I don't like it much either. But you could argue that Bitcoin is an ideology, Stoicism is an ideology, Free Market Capitalism is an ideology, Free and Open Source Software is an ideology.. so it seems to me that just calling something an ideology does not suffice to dismiss the set of ideas under that umbrella.
Rather, blind faith in ideology, or following ideology because it's cool (or so they think), hip, fashionable... in short, for any reason other than considerate and extensive rational thought, seems to me to be closer to the true source of the issue at hand.
Thinking is hard, checking a bunch of ideological checkboxes is easier. I can see how this would muddle the waters. But it does not - in my opinion - have to be so.
