Luckily, when I did vipassana, I was in a group that did not insert much religion in weekly practice or retreats. Sometimes, there were separate reading groups for people who were interested. But practice was only sitting, walking, sitting, and then the opportunity to tell about your experience if you wanted to. I think another problematic aspect (besides religious dogma) is the hierarchy that exists in some communities. While I definitely think that it's important to be guided by an experienced meditator, some leaders are (unjustly) put on a pedestal (even more when they are from the east). This leads to people accepting practice (or even sexual abuse in some cases) without critical thinking.
