Controversial opinion: In some regards, YES
Trump is a silver lining. He has exposed the GOP for what it is, a bunch of racist, greedy pieces of shit. They've shown their true colors and intentions. They have nowhere to hide. If Democrats and progressives play their cards right, this could be the catalyst for a new beginning, finally ushering in the social and economic change we need to move foward.
Hillary would have effectively been an extension of Obama's center-left/ moderate policy and presidency. Everything at the surface level may have been okay, but there would be far more underlying hostility and bad blood brewing. The right wing would be even angrier and unhinged than they are now. Now imagine that entire base and movement, lead by a candidate who isn't a dumbass like Trump, who truly knows how to game the system.
