@Joseph. That is actually not what he stated. Its right above. I quoted what he stated. His words were “A reform temple has the same halachic status as a church,…” This is not accurate.
A reform synagogue may be just fine if they are considered tinokim shenishba. You want to agree with those who argue that a reform synagogue is heresy, (many of which were penned at a time when it contained rebels as opposed to today’s population of people who do not know) you are entitled, but it still does NOT have the “same halachic status as a church” according to the majority opinion (which I suspect you agree with) that a church is avoda zarah.
