Seconded that you should refrain from such comments.
This is a community of history enthusiasts, and some are liable to take umbrage with claims like that. While it is true that the ancient Jews did suffer long periods of foreign occupation throughout their history, so did almost everyone else in the region. And during their periods of autonomy I think you would be hard pressed to argue they were perfect models of principled restraint. They did their fair share of conquest and war crimes to their neighbors, just like their neighbors did to them. It's well documented in the Tanakh.
You are free to believe whatever you want, but if you wish to participate productively is a community like this you need to follow certain rules. Those rules are set by the majority consensus. They include not casting blanket judgments on the moral worth of any ethnic group relative to others, and not judging the behaviors of ancient peoples by modern standards. And more broadly, where no consensus exists on standards of behavior or acceptability, we default to a permissive standard that prioritizes historical accuracy.
Thus it doesn't matter whether you believe the portraits are modest. What matters is that there's no majority consensus about what modest is (beyond possibly a bikini level of minimum coverage, and even that might be contentious), but we do know some ancient (and modern) groups followed different conventions of modesty. So what we have now is the right standard. If you don't like it, make a mod.
