Trying to sound reasonable is far from the same as trying to be reasonable.
If they were trying to be reasonable they wouldn't be centrists, they'd be as far away as possible from conservative, corporatist parasites, fascits, and similar critters, instead of trying to appease them.
But of course “centrists” aren't trying to be reasonable. “Centrist” is just the label those parasites use when trying to disguise their nature from their victims.
