Or is it just the largest ones that need a minute?

I'm not in strong disagreement, because I genuinely believe in respect for the victims and their lives ones, but I'm a little bored of "we can't talk about it right now" constantly being used to stop the dialogue while people are angry and feeling proactive. Based on those I saw posting that all day, it seems equally political - it's best to halt the ongoing conversation during a tragedy, because it favors the other "side".
