Making a throwaway and arguing the points as vaguely and indirectly as you are with it - combined with your focus on derailing conversation with tangent about politeness or whatever is certainly not helping the situation. There have been a lot of "green" accounts arguing very incoherently based largely on appeal to emotion in the last several days - I agree it's frustrating and very distracting from the usually high level of discourse. However the topics are also something a bit new for this place - extremely relevant things about policy that affects the community a whole, wrapped up in national discussion and culture wars, so there is some adjustment required.
Your actions of creating a throwaway to preserve karma or keep people from knowing your actual thoughts are contributing to the problem you are complaining about.
How should I react to a brand new user account - actually a whole set of them (not that any others are you, not accusing you of that) spewing vitriol and vague stances, and engaging in seriously poor debate form? My initial and continued reaction is that they are some form of sockpuppetry.
