That interpretation is entirely too generous. That expression "Silence is Violence" is explicitly intended to compel speech and its clear meaning is that if you don't, you are contributing to the violence against minorities.
This is not an extreme example. The expression has always been used (at least in the current climate) to mean, you agree with us, verbally and visibly and loudly, or we attack you.
Edit: If you think the above example is not an example of what "silence is violence" means, by all means, explain why rather than just flyby downvoting.
