They've published op-eds by John Bolton, Vladimir Putin, and a bunch of other boogeymen over the years. I don't think it's about subverting accusations of liberal bias. Their editorial board is unabashedly liberally biased. I think it's more about fulfilling the whole "all the news that's fit to print" thing. In op-eds like these, they're happy to sit back and watch the commenters lol it into oblivion.
