The sad reality is that, although as a rule the Yeshivishe oilem respects every person (MO, DL, etc.), this does not apply in reverse. (On the internet itself it seems every day there is another MO blog that its main point is to attack Chareidim and Rabbonim, competing who can be more vicious.)
If you want to know how the Yidden looked in the time of the Beis Hamikdash, the best picture today are the Yemenite Jews – who were left untouched for millenia – with their long payos, etc.
