Counterpoint, I drink over 2 l of soda a day almost every single day, I have not had a cavity in the last 7 years, and my enamel is amazing.
I said all of that to say there is a genetic factor to consider, and if you are having enamel issues because of sodas then you would have likely also had them because of tomatoes and other citrusy zesty and acidic foods.
You can't just blame the soda, although I will admit that I'm sure my teeth health would be better if I did not drink so much soda.
