There are times that we seem to be reflexively against certain things that we forget to remember what we are for. A related problem defending our side from foes is more important from advancing the virtues of our side.
Current presidential politics is a low-hanging fruit on this front. Conservatives don't like leftists and like leftist elites even less, so anyone who dislikes leftist elites and the causes they sponsor (globalism, multiculturalism, open borders, big government) must be doing something right.
If the anti-liberal critic is doing so out of a self-centered clannishness that distrusts people who don't look and sound like you and wants small government not for the greater good but for a greater bank account, they might have a common enemy but they might not be all that good of an ally.
Trump has done well bashing the people conservatives, especially ones with an ethnocentric streak, love to hate. This works two ways, as liberals will bash certain real and perceived oppressors out of custom as much out of making positive change. A good liberal will happily bash big corporations on their iPhone sold to them by the biggest corporation on the planet (at least based on market cap).
A good case of enemy-bashing showed up this morning, as Drudge was belittling dire warnings over Hurricane Matthew by NOAA as some sort of global-warming marketing scheme. On climate change, NOAA can err on the side of being a pro-AGW apologist, but their day job of predicting the weather they do fairly well, they're one government entity that is rather effective.
However, if you come from a knee-jerk government-hater perspective, you reflexively scoff that anything good could come out of Nazareth, er, the government. Yes, it can. Does government over regulate and mess things up at times? Yep, but some government functions do their job and earn their paychecks rather well.
Matthew seems to have stayed just out to sea, sparing the Florida coast (and parts inland) a direct hit from the eye-wall and full storm surge for now. However, had the storm veered a bit to the west, it would have been a different story, and given the margin for error on weather-forecasting, you need to note the killer possibilities and breathe a sigh of relief if if isn't quite as bad as feared.
