I am not sure what you may mean by conservative, given the notion varies wildly depending on a number of conditions. In any case you are more than welcome to embrace whatever beliefs strike your fancy (who I am to stop you?) and I've never used the thumbs up / thumbs down, ignore function, etc. with any poster.
Talking about political ideologies, I would suggest you abandon them and rely on a zesty recipe of logic, supported by science-based evidence, spiced up with a dash of humanitarianism. I would further suggest that "sentiment" (a view of or attitude toward a situation or event; an opinion) is nothing more than that without logic supported by science-based evidence.
As to humanitarianism, it could be argued that it represents a non-science-based, non-evidence based ideology, but I can live with that given the inevitable fact that I am a human being.
