Be a bomb thrower; blow up ever notion that is not conservative with facts. Snipe at everything that you see as being wrong coming from the libs, as well as the repubs. Make your non-conservative friends dread discussing politics with you, because you are so militant. They will either shut up because they have no facts, or become informed on the facts; destroying any liberal notions in all but the most hard core leftists.
Take a note out of the left's playbook. Show the people that the government can not and will not protect them, and is in fact doing them harm. Point out to every black you know that the dems have kept them on the government plantation (use those words) for generations. Point out to any Hispanic illegal that the libs do not want them to succeed; through their policies of non-integration they want them to remain "poor, dumb spics" instead of Americans. Point out to the affluent middle class white you know that the libs want to pay for their social experiments with their money. not the ruling elite's (that ought to be easy with Fienstein, et al as your reps!)
And please...no pastels ;-)
That'll be the day. Most non-conservative friends I have won't shut up. I tend to keep my mouth shut unless/until somebody shoves their crap in my face- as is happening more and more frequently. They have been doing what you advise (what I quoted above) but from a moderate to left POV.
My prime local example is Wayne Gilchrest (RINO-MD) and now (thankfully) ex-Congressman.
I'm sick of it.
