it doesn't sound like you enjoy fighting Russian military, why should I?
As for silence, I've been helping Russian opposition financially for years (even when it became illegal, through different channels), talking to relatives and friends to make sure they know what's going on.
At some point risks become too great. Imagine Maidan, but if Yanukovich won and had 8 years to surround himself with 100 times more military and propaganda.
Call me a coward for wanting to have a normal life.
