The natural default position on most anything is liberal. Quite easy to fall into.
The values and principles of conservatism like rugged individualism, economic restraint, small govt and personal liberty must be taught. They are not passed down through the genes.
Rather than equipping children with the tools for critical thinking as used to be the norm, the default position is now taught and re-enforced and allowed to stand by parents who accept schooling as their "baby sitters". Backed up by the ministry of propaganda aka the MSM. Thus we get the over whelming numbers of golden calf worshipers.
Being conservative requires reason and logic. And being able to explain your position logically. Being liberal simply requires "feelings". The default position is a much easier road to take.
