I like sodas and actually I can see how all of those would be appealing.
It's a holiday pack with flavors like "gingerbread cookie", "candy cane", "sugar plum", and "pear tree." Lovely, right?
Soda is definitely empty calories....but not unenjoyable to some of us. What is obnoxious is people shoving what you don't want in your face after you say "no thanks!". It's equally obnoxious to say "Oh that stuff is nasty".
It is human nature to want to share what you enjoy with people. It's a two way street though. You should politely decline and they should desist. Being rude about food choice is becoming epidemic. I remember eating a tofurkey sandwich at lunch a few years ago and this bitch, every day would let me know that "That is just foul". OK, fine, I'm not even offering you a bite, but must you be unpleasant? It looked like a plain sandwich, no odor. She also did WW and LOVED to critique the point value of people's lunches. "That is so many points".
Unless someone comes to you and says "What do you think of the taste and nutrition value of these Chips Ahoy?", just don't say anything. No one actually cares to be educated. If someone is an actual asshole about offering you food, sure, be an asshole back, but "Yay, my holiday soda came, would you like one?" (or "I baked cookies" or "Have a slice of my mom's fruit cake"is not being an asshole and merits a response like "No thank you, you enjoy!". "My holiday soda came, you are an IDIOT to not want some are you surrrrrreeee you don't, why do you follow that crazy diet" is being an asshole.
Everybody enjoys a different mix of foods and no one has a "perfect diet". Also, no one has the same palette. Just because I don't like beer and margaritas doesn't mean I am somehow superior over in my chair swilling vodka and club soda.
