"Aren't you just getting offended on behalf of other people? Would you take it yourself? No? So what's the problem?"
Interesting point. Is it my responsibility to protect the foolhardy? Does it really do any harm? What's the harm in Homeopathy?.
The person was more making the point that one should share knowledge about how crackpot it is, so people can judge for themselves, rather than try to stop it directly. So, I recommend we make more jokes about it.
On the occasions that my girlfriend drinks a mug of boiling water, we always refer to it as homeopathic tea. I recommend you do the same.
Also, I recommend you refer to mediums as being "guessers" and reflexologists as "foot-fetishists".
