Is it wrong that I hate alcohol and I think people who drink it irresponsibly are plain idiotic?
I don't know if it's wrong. Could you explain why you hate alcohol and consider drinking idiotic?
Because it's idiotic when people drink too much and aren't responsible for their actions, or they try to drink and then drive.
While you should understand that not everyone agrees with you that drinking is wrong, it is not bad to have a strong opinion. It is generally a bad idea to get really drunk, and wanting to avoid that yourself is perfectly reasonable. Just be careful you aren't being too judgmental of others.
I'm only judgmental of people who get drunk all the time.
I see where you're coming from, but even people who get drunk all the time deserve some compassion. Alcoholism is a terrible thing, and it can be difficult for people to stop once they start.
