I used to subscribe to that idea, in that I didn't want extremists to have a platform, but it seems like they got one anyway.
Now I'm of the mind we need to lean further into democracy. Some thoughts:
I think part of democracy is concensus building - how can we build large majorities around policies we care about? The media does somewhat 'naturally' gravitate towards wedge 50/50 issues. We should be putting these aside until we reach larger agreement, and focus on the issues more of us agree on, I find it hard to believe there aren't enough of these to keep folks busy.
We need to accept that democracy has cost and can be slow - but it is the way regardless.
Federal government should probably be handing some powers down to provinces, provinces should be handing powers down to municipalities (or giving them back in some cases). Instead of a thin pool of insiders, a broader pipeline of leaders.
We need to ask more of our politicians but also give more.
And yes electoral reform.
A) tax revenues greater than 10% of the market (e.g revenues over 10 billion dollars get taxed in a 100 billion dollar market regardless of income)
B) the government should fund the development of more wholesale markets.
