This is where the problem lies within our current political discourse: both parties have fundamental differences within themselves on what they view as being morally on the up-and-up.
Both parties view certain demographics in their own way and this allows them to engage in policies that allow them to accomplish their end goal while never causing harm -- because they genuinely believe they are not causing harm to anyone. They're only following through on policies that match their moral compass.
Until this country has a reckoning on what its fundamental values should be, there will always be a sense of distrust and skepticism between each other.
