OK, I'll bite: I upvoted your original comment, then downvoted this one: It doesn't contribute to the discussion at hand, and I don't have much interest in promoting the viewpoint of someone so entitled that they think it makes sense to unilaterally dictate the terms of a discussion they're having with total strangers, then call people cowards when they don't obey. Being ignored is not being silenced.
fair enough... but... down-voting isn't to ignore. To ignore is the right way if you have nothing to say.
I like your comment. In my defence, I responded within the context and referred to original rules by PG rather than trying to dictate the terms myself. Thanks for the upvote and the response.
