I think it's important to look at the whole spectrum. Are people putting themselves as superior for using psychedelics? If so, I don't think they've really delved deep enough into 5-ht2a agonists to even get the message
If they're putting psychedelics up as superior to other drugs - why not? Everyone has their drug of choice. The important part is to accept other peoples views and not just blatantly demand that psychedelics are the truth, the way, the light, and that anyone disagreeing is, simply put, wrong
Let's look at the reasons why they might put psychedelics on a pedestal though.. Firstly, psychedelics come with far fewer side-effects and dangers than most other drugs (with a few exceptions of course). Secondly for many (or even the majority of) users they actually come with an overall positive impact on the user's life.
Along with this, I think a large part of putting psychedelics up on a pedestal above other classes of drugs is about how deep the experiences are emotionally - how often do you here someone talking about the day coke changed their life, without it being a horror story of how they almost killed themselves and decided to give up drugs?
I think it's partly just respect, when a chemical can delve so deep into your own mind, show you things about yourself that you didn't even realise yourself, and completely and utterly change your perspective on life and the universe - it's only nature to give a bit of a bow and show it extra respect.
On the flip side though that can be negative too, as humans we often attribute anything unnatural to some sort of super powers to be revered, and many people do this with psychedelics, but really, to each their own, if they're not harming themselves or others with these beliefs then good for them
Though, regarding looking at the full spectrum, it's worth noticing how many people are the same with other drugs. Look at how many people who smoke Cannabis are convinced that it is the most special drug, and often look down on others for consuming other drugs - the latter part can definitely be said of alcohol, cigarettes, and caffeine. I know many users of Cocaine and other stimulants who are convinced their drug of choice is the best and superior to all others.. etc.
