Views on Reproductive Health Bill
As the advocacy chair of the Catholic Education Association of the Philippine, Tabora supports bishops in opposing any law that includes provisions for "abortifacient" birth regulation, which forces Catholics "to act against his or her conscience" and "usurps" parents the right to educate their children on sexuality, but not everyone in there is Catholic in a "Plural" society people should have to come together and understand what is the demand of common good.
