In my own particular church context, I find that one may theoretically offend everyone with liberal views. Let me explain with two examples:
First, I liberally hold to the belief that the Sacrament on the altar, or Eucharist, is the Body and Blood of Christ. The catechism of my church says the same thing in so many words. While this is the traditional view of the Eucharist, many Christians who call themselves "conservative" reject this view. Hence I call this a "liberal view."
Second, I liberally hold to the view that the Church has the freedom and right to hold to and teach distinct views on matters such as pro-life, marriage between a man and a woman, etc. When and where secularism, or culturally based Christianity, seek to impose other beliefs on the Church this imposes on religious freedom. Here I liberally depart from traditional "liberal" or "progressive" correctness.
Theoretically, or maybe realistically, one may bring offense to everyone. It's OK.
