Hehe, I don’t know who this is, but it was fun to watch. “I’m a kind of Stalinist fascist ... if I take drugs, then I become passive, and enemies can attack!” LOL!
So, the argument he didn’t even attempt to address in his comparison of smoking to other drugs is that smoking hurts other people directly, while other drugs don’t. The primary reason we have rules against smoking in public is it’s effects on people nearby who are not choosing to smoke. This entire thread was about secondhand smoke, and Zizek didn’t address it.
Similarly, the reasons we have some regulations on smoking in private, and the entire reason we have regulations on drugs is because of the direct damage it does, statistically, to the users, and to the indirect damage it does to other people. For the minority of bad cases, hospital visits for overdoses and car accidents, social services for addicts or their children, rehab, and loss of jobs are real issues. For the larger majority there are still measurable effects on drug users’ lifespans and on the economy.
We are a collective and have no choice about that. We have some shared resources that we need to agree on. If you want to enjoy freedoms, you have to respect other people’s freedoms. Where’s my freedom to breathe clean air if you smoke near me? (I happen to have some athsma, the risks to me of secondhand smoke are greater than mild exposure to carcinogens.)
So yeah, not only is it not a proof, it’s not even a reason to buy the argument that anti-smoking sentiment is ideological. To prove that it’s ideology, you need to demonstrate that smoking is safe.
