The party of no has a vision problem. It seems like every issue with them is a rung on the ladder to hell. Gay marriage will lead to reckless hedonism. Increased government spending of any kind leads to socialism. Marijuana decriminalization will turn every street into a shooting gallery. Government regulation of industry will make our government a inflexible nanny state.
Alliteration doesn’t make it true - some slopes aren’t slippery. We have far too many people in prison for nonviolent, victimless drug offenses for non-harmful drugs like marijuana. Releasing them (or not arresting them in the first place) doesn’t turn the country into a drug-addled cesspool. Increasing regulation after years of free market abuses is just part of how we find balance in the necessary relationship between business and government.
Some “slippery slopes” aren’t even slopes at all. Gay marriage adds order and stability to same sex relationships that are completely legal regardless of the definition of marriage. Gay couples already engage in all the practices of married couples - cohabitation, sexual intimacy, raising children, buying property. Giving them the same legal status as opposite sex couples would, if anything, be a conservative force in their lives, not a recklessly liberal one.
If you’re going to make an argument not against a policy itself but against where a policy may lead, you need to make sure the policy actually leads there. In many cases, these potential threats are imaginary and reactionary.
Teen suicide has fallen by 25% over the last decade. Fewer teens are having sex, more of those that do are using contraception, and fewer are getting pregnant. Fewer people are smoking. Alcohol related deaths are declining. Yet you’d hardly know it from the way those issues are handled by conservative politicians. Every report is a startling revelation about a supposed decline in morality and it’s always linked to liberal policy. But the numbers say something else.
Every study on sex education shows that the so called “explicit” sex education in schools leads to better, more responsible behavior by teenagers, while abstinence education leads to more Tripp Palins. Marijuana decriminalization leads to decreased recidivism with no increase in violent crime. Greater government spending on infrastructure has been a boon to many industries, in some cases making commerce possible where it once was not. And increased regulation in those industries allow them to compete fairly without having to exploit workers and the planet in order to get a leg up on the competition.
Public policy is a complex, intricate, delicate thing, and making policy based on guttural reactions to social outcries without regard to established policy research is childish (or in the GOP’s case, senile). Leave it to the adults.
