What you're effectively saying is that conservative philosophy has no appeal or persuasive power, that it's impotent and inert - one is either born with it, or one will never get it - which essentially means that it's a nullity, that it'll die with the present generation. If that's the case, then all the more reason to push conservatives and conservatism to the side and move on with something that will have some lasting, persuasive power.
To certain sectors, that is absolutely true.
Furthermore, if the lure of "freebies" is irresistible, then why are any of us still going on about the vices and practical impossibility of "freebies"?
That answer is easier. It's because not everyone is a member of those sectors that are all doped up on freebies.
Unless we're some sort of superhumans (I, for one am most certainly not), we should all have fallen prey to the siren call of "freebies." But we haven't, which suggests that the lure of "freebies" is not as all-powerful as you suggest.
As the overall population is dumbed down further and further, the drug effect of freebie-ism becomes more and more prevalent and powerful.
....there is every reason to believe that an appeal to "minorities" that lays out conservative philosophy in plain English could very well persuade them of the superior benefits of said philosophy over the false seduction of "freebies" offered by progressives.
Over a period of time that may be correct but, not by 2016. You can start now but doubtful it will have any effect on certain freebie drugged sectors.
