Alberta passes law allowing parents to pull kids out of class

A written notice required when sex, sexual orientation, religion are covered,its sad that residents of Alberta feel its necessary to pull their child out of class when any of these subjects are being taught,this just shoes how narrow minded Alberta residents are,i think it would be educational to learn other cultures and religion,to better understand to our fellow man,but im not surprised,this is the same province that has a culture of white supremacy on the rise.How can this be a thread to the child,why take them out of class why remain ignorant towards these subjects when they are taken up,all they are doing is alienating themselves from the rest of the country which is soon or not already dominated by a mix of other cultures and religions,sex well,the kids can learn in school or by their parents or out on their own.
