Considering the present regime is anti-church, anti-semite, anti-Russian, and anti-Crimea, it does not surprise me that folks would be supporting anything pledging to remove that. Though misguidedly.
They are not misguided in the least, no more than your knee-jerk reflex would be "misguided" when your knee is tapped. What they are doing is demonstrating civilizational solidarity [maybe even unity] against a regime which desires to move away from the orbit of that suboptimal civilization.
