Look man, I get it! You're 40+, set in your ways, unwilling to change. You already set all your beliefs! Why go around questioning things and thinking about WHY you believe something? You've survived this long, haven't you?
However, if you WOULD like to spend even 1 minute in critical thought about whether you're being delusional or not, I would highly recommend you do some honest research on the molecule monosodium glutamate. Try to stay away from (or at least honestly question) yellow scare propaganda from your youth, and look to contemporary studies on the use of MSG.
Hopefully, you realize that MSG is just savory salt. It's a seaweed extract. It's entirely harmless if ingested in the same amounts that people ingest table salt.
I hope you take the time to combat the propaganda of your youth and come back to this thread more mature and less delusional.
Or don't. Not really my problem.
