No, its fine. Im introducing concepts.
If we talk about eating habbits, or choice in sex partners, we are not talking politics anymore. Politics (in democracies) is 'talking about stuff' to keep a general informed consensus. But that 'private level' stuff usually is separate (by design).
If you have people making decisions by the color of a cap, or how a person eats his steak - thats not in 'the interest of this concept we call democracy'.
To bring the Winston Churchill example, he was an unpleasant, flawed man - he was a very good politician though. Thats also, why this separation is in there basically.
To 'kill of' people because of 'what they did in private' (think golden shower) is more a staple of dictatorships (and there people that have fallen from grace - only).
So its important to acknowledge, that some stuff is private not to step into the pitfalls of 'humans rather would discuss all day who is screwing who, and how deep and how obviously amoral' (the facebook 'we optimize by clickrate' conundrum..
) - because that actually halts public political discussion.
