Most particularly, the government and its agents are not free to single out adults for their private and consensual sexual conduct in their bedrooms, or for their speech in that regard. The most basic freedom is the freedom to be left alone by the government. The Supreme Court might disagree, but then again it is now in many respects a party to the diminishment of rights enunciated in plain English in the Bill of Rights. This special attention to gays also amounts to selective enforcement. Please note that the option of free speech is always open.
People can demonstrate and talk and express their views, and attempt to convince others.
The low road is when some group attempts to use its political power to get other people, usually law enforcement, to enforce their own views of morality in private, consensual conduct. I cannot comment on it now, since I have not yet seen it. I hope it will present factual information on the dangers of drugs and the options for treatment. I also hope that legal drugs will be given the same treatment in accordance to the risk they pose to individuals in our society, and that a distinction will be made between adults and children. The United States continues its headlong rush into authoritarianism, at least in the public realm.
