It’s a shame to paint ‘all of Mexico’ as a serious problem. There are plenty of areas that are perfectly safe (safer than most US cities).
You go right ahead and believe that, and act accordingly.
I saw the handwriting on the wall and stopped traveling to Mexico in 2000.
I am fluent in Spanish, but always hide the fact and some of the conversations and comments I "accidentally" overheard would curl your hair.
Life is too short.
