Earlier quoted context omitted.
The most charitable hypothesis here is just libertarianism I think, especially because of its ideological prevalence in this crowd.
There's a libertarian-socialist horseshoe on age of consent laws. The more ideological one becomes, the more passionate they are about lowering the age and distinguishing between the different paraphilias relating to sex with minors. At this point I assume that all political theories are invented to justify their proponents' sexual desires.
Also small nitpick but one cannot be "more" or "less" ideological, we all are whether we like it or not, it's just the question of which ideology you are. You might say, "well I am not one of those fanatics on either side of the horseshoe," but that doesn't make you "less" ideological, it just defines your ideology.
Ideology =/= belief system. It is rather the implicit, subconscious framing you have to the world that informs the belief system you arrive at ("rationally" or otherwise). So, in fact, denying you have ideology, or having "less" ideology than the radicals, shows that the influence of ideology on you is stronger than otherwise :).
