Pretty much just setting yourself for a life of constant irritation, bickering, etc.
But you don’t want someone that agrees with EVERYTHING all the time, either.
There’s a balance to find, in life, in all things.
I’d rather be with a rabid Islamist than a liberal, if those were my two choices.
Why? Two reasons:
1. As perverse as it is, the Islamist has a belief in a god (lower case on purpose). The standard liberal has no belief in anything but “the state”.
2. The rabid Islamist would fight to the death; I can respect that more than the liberal t**t SOP of hiding behind bullshit decrees passed down by tyrannical judges.
