Sadly, there might be only one way: direct demonstration. I hope they see the light before that happens, though.
..To them, like to Stalin. One death is a tragedy, a million is just a statistic. Islam and "liberalism" are both death cults but the liberals want it to be to others not them. Stalins attitude was unrestrained liberalism. Thats why he liberally murdered OVER 100,000,000 of his OWN people, some say more. To a liberal logic is reversed in the direct scope of how liberal they are. Stalin was very liberal as was Mao, and Pol Pot. And every Open government except they still have some restraints.
..Thats why liberals and Islamonazis tend to be allies. The Muslims were allied with Hitler. They knew Hitler hated them too, but Hitler hated the Jews, more, they thought. The Muslims haven't figured out yet that the liberals would nuke em all in a New York minute. Its the people the Muslims HATE that care about their lives. If liberals ever get absolute control of the world. The Islamic problem will be solved, not in Islams best interests. One World government will solve the Islamic problem and accurate logic problems too.. Did I say, Liberals have reversed logic to good is bad and bad is good. Ah! yes, I have.
"Liberalism" is not a mental disease its a social pathological disease. The next liberal you run into is not merely a misguided individual but a threat to the fabric of civilization. TOO MUCH you say.. Actually I was being nice. Read between the lines and my real attitude will surface.
How "liberal" are YOU ?. Socialism is only a symptom.
Tell them the terrorists are both pro-choice and pro euthanasia but differ from liberals and Euroweenies only in that they prefer somewhat later late term abortions than do liberals, and somewhat earlier euthanasias than Euroweenies, though the terrorist will happily accept any deaths also considered acceptable by liberals and Euroweenies, too. The folks you want to inform should get the picture.
