Reform is koifer toras moshe misinai. They claim that the Torah was written by human beings ch”v. We are forbidden to enter into their temples the same we we are forbidden to enter into a church.
As for your question about taking money from a church, there are various sources that discuss this. However, based on your post I assume that you wouldn’t be interested in hearing the correct answer anyway. Maybe you can organize a “debate” with a Rov on the subject.
