Both may have a whisper of truth behind them, both may have some adherents, but the numbers have been blown out of proportion because it's politically useful for some people to invent this boogieman.
That's a remarkably uncharitable attribution of motive. Sometimes people jump on an idea because it seems novel to them, or because it seems like the most significant - but not only - thing, or because it seems easy. Those might not be perfect strategies, but there's no need to assume malice or conspiracy.
What other issue do you think people should focus on instead? Wait, don't answer that. First, why do you think you should have a say? One of the beautiful things about a democratic society is that a million people can have a million different ideas and priorities, many of them seeming "wrong" to someone else, but all tolerating each others' "screwed up" ideas anyway. How does concern trolling fit into that model?
