Divorcing and re-marrying is one thing.
Having simultaneous wives is something else altogether. It's a bit low in my opinion.
I get the feeling that a polygamous man would probably love himself more than any of his wives.
Having an out-of-control ego is one of the worst things that can happen to someone as it tends to have devastating effects on those around them.
Yeah. I don't understand how he could look a woman in the face and say "goodbye" so he can go off to his other wife/wives. Oh yeah, that's right - Allah says it's OK. So it must be OK! Islam is perfect after all...
Funnily enough Islam does accept that polygyny is unjust.
4:3 And if you fear that you cannot do justice to orphans, marry such women as seem good to you, two, or three, or four; but if you fear that you will not do justice, then (marry) only one or that which your right hands possess. This is more proper that you may not do injustice.
