Let’s take it point by point (by the order of importance):
1. Abortion - taking somebody’s life or supporting somebody killing somebody is not a libertarian philosophy. A libertarian would want his government to punish the murderers, because the government exists solely to protect life and liberty and facilitate free market economy. In this case, killing an unborn would be murder and the libertarian government would prosecute the murdering mother and doctor to the fullest extent.
2. Military - a military exists to protect the life and liberty of free people. If those join the ranks meet the criteria (ability to defend freedom) then they should not be barred in a free society. If you believe in freedom, which logically includes freedom to be a flaming homo, it is your right as well. As long as the flaming homosexualism does not prevent you from taking arms against the enemy, then why put constraints?
3. Marriage - first of all, why is the government in this marriage business anyway? For tax deductible reasons? If so, this is the biggest scam ever. Let people decide what marriage is, not your government. It is ironic that “limited government” conservatives want government to dictate to them what should be the most intimate personal decision. If you keep government out of marriage, this “gay marriage” scam goes away anyway.
4. Drugs - you cannot stop people from hurting themselves. Why stop at drugs? Why not alcohol or tobacco? Liberals want to ban those, as well. A libertarian would look at the drug laws in the country and see an out of control government encroachment.
Did I cover all your “concerns” about those evil libertarians?
It isn’t government so much in marriage that is causing the problem. It is the damnable lawyers. Lawyers run all branches of government to their advantage. This profession is most responsible for our decline.
