Mexico tends to be conservative, Queretaro is in the part of the country where there are even a bit more so.

The only really liberal place in Mexico is Mexico City itself, there they recently established same sex partnerships and relaxed abortion laws (but there is a complicated Constitutional legal challenge regarding this, in general terms a woman can abort in very restricted circumstances, and even then the amount of bureaucracy means that the only practical way is to find a sympathetic private clinic, which is not easy, or to go abroad).

Keep in mind that laws change from state to state, the only way to be absolutely sure about any legal matters is to refer to a local lawyer or local Women Rights organization of some sort, my gut feeling is that Queretaro will not be in the forefront of Women Rights issues.

Mexico is a great place to study arts, but again I would think more about Mexico City, where there are multiple very good academies and universities, and where they would be more tolerant with artistic eccentricity :-) Queretaro City is not known for its arts institutions or educational system, but I would explore first before passing judgement.

In Queretaro itself it snows very rarely, during the summer it is sunny and can be quite hot, it has a typical semi-arid climate.

Mexico has an international policy of not interfering with the internal affairs of other countries, it is always strongly opposed to military interventions of any kind (we voted against the invasion of Iraq in the UN's security council) and more often than not shuns dictatorships: Franco's Spain, Pinochet's Chile and Apartheid Southafrica were never graced by a Mexican Ambassador ( the glaring exception being Cuba, but in Mexican politics the non interfering is sacred and takes precedence over other concerns). This is ironic if you consider that our government for many years remained in power by tactics that were as dictatorial as the finest of some of those countries.
