I do retract my complaint about comparing politicians to programs. In its place, I complain about the process of electing a President being different from voting on an init system.
The most important point here is that distributions vote on which init system they elect. We are not all electing one init system to rule them all, across Linux. Distributions are nation-states of varying size that follow similar but sometimes incompatible rules, all derived from the same core tenets and program. So we're electing governors from the same political parties, more or less.
I think telling people to suck it up and just accept systemd as their one true init system is just silly. Regardless about how you feel about Clinton, there are always reasons to use something else.
If you need a barebones system, or something for experimentation, or something that is hardened at the price of flexibility, that is an applicable choice, and one you can make from the comfort of your own home. You can't fork the US or an individual state in the same way you can download a different distro to your Raspberry Pi.
And I could go on and on. But you're right; I suppose I could, in the end, begin to describe how silly that comment was. Even if the explanation ended up being really unwieldy and not my best writing. It might not have been wholly constructive either, but we're generally all here to have a good time.
My point is, it's a silly, leaky metaphor. And telling people to suck it up and use an actually useful tool in the comments for a distribution that's written as an elitist hobby project is similarly silly. These people aren't picketing your Debian or Arch systemd parties. They're just doing their own dang thing.
