> blanket regulatory attitude across the IT spectrum

That's jumping to conclusions. I didn't elaborate at all what kind of regulation I support or how granular. I now feel that my comment wasn't up to the standard, because it has a bad mix of off-topic and terse "snarkiness".

As to the usage of downvotes, of course you can use it however you like, just like you can dismiss anyone you like whenever. I'm referring to a common _regulation_ in communities, that a comment shouldn't be dismissed if you don't like it, but only if it has a negative effect on the discussion.

What do you hope to achieve by downvoting those you disagree with? Force their opinions to the bottom of the discussion stack? I.e. silence them? That's what you're effectively doing, and it's not conducive to a healthy community.
