I cannot begin to imagine what it must fee like to choose to say their Guru is wrong and that their practice in Dorje Shugden is wrong... some are really old monks who are ill and have no where to go, they are being forced to a cornered. It is definitely not an easy choice and I am sure some of the senior monks do secretly still practice Dorje Shugden.
I am sure most of them are not happy with this forced vote and I can only try to empathize with them. Hence those who can step out and say stuff it to the CTA like Kensur Sonam Gyaltsen need to speak up more for those who cannot have a voice. I guess this forum is one of the many ways we can raise our voice, thoughts and opinions.
