One obvious reason why this might be the case is that the various implicit norms surrounding political discourse actively encourage tribalism and cognitive dissonance (“Hey! He’s a flipflopper!”) more so than in other areas of discourse where some of these pressures are lacking or in some cases (such as academia, to some extent) deliberate effort has been expended to create counter-veiling norms to these trends. As long as political discourse involves politicians and politicians owe their careers to the exercises of obfuscation, pandering and appealing to vested interests it is doubtful this trend can be corrected. As a general rule you should examine your own attitudes and if you find your view entail that those of an opposing political conviction to yourself must be actively scheming to cause damage to the country (as opposed to simply being mistaken or biased) you have probably made a mistake somewhere.
