The anti-hijab/burqa argument is that the government is trying to mandate public areas as a safe space for liberal leaning Muslim women who don't want to wear traditional garb but are forced to by community or family pressures. Because the government bans it, the community anger is then directed toward the government instead of the individual Muslim women who then enjoy the freedom of not wearing it.
The pro-hijab/burqa argument is that if a community demands their women to wear traditional garb or face ostracization or punishment, and the government bans that garb from public places, the women will then simply be banned from going to those public places altogether. In which case the only end result is further antagonizing the Muslim community.
In the end I think the pro-hijab/burqa argument is most rational. Western nations need to maintain their liberal values of freedom of expression and religion, even if it can be argued there's a kind of stockholm syndrome going on with garb (particularly burqas) that was objectively created to desexualize and subjugate women.
