> But the simple fact is that slavery was a fact of life in Paul's day, and he had to deal with the world as it was.

Weird how this only applies to slavery, though. For every other aspect of life, Christians aren't expected to simply accept the evils of the world as immutable and unchangeable.

>And, frankly, his advice to slaves is good advice.

No, it isn't. The only good advice for slaves is to cut the throat of their master and be free as soon as possible.

>Notice that this is far more than a one-sided "women must listen to their husbands" that it is often portrayed as.

It is very much that, according to 1 Timothy:

    A woman should learn in quietness and full submission.I do not permit a woman to teach or to assume authority over a man; she must be quiet. For Adam was formed first, then Eve.  And Adam was not the one deceived; it was the woman who was deceived and became a sinner. 15 But women will be saved through childbearing—if they continue in faith, love and holiness with propriety.

> Even if one doesn't like traditional gender roles, it is disingenuous to portray this verse as some kind of misogynistic oppression of women.

It has literally been the basis for the misogynistic oppression of women for more than a thousand years.

That's just fact. You can spin it any way you like, but the purpose of a system is what it does, and violence against women is what these verses do.
