"I know that some people are adamantly opposed to cruising, and that's fine, but I like to learn about other people..."
Yes, it's a bit of hyperbole, but not a ton...
"I know that some people are adamantly opposed to genocide, and that's fine, but..."
"I know that some people are adamantly opposed to blood diamonds, and that's fine, but..."
"I know that some people are adamantly opposed to clear cutting the rain forests, and that's fine, but..."
"I know that some people are adamantly opposed to hunting elephants for ivory, and that's fine, but..."
What I'm saying is that none of those things are good.
Cruises are not good. They are the opposite of good.
This is an industry that is about to dynamite miles MORE of coral reef on Cozumel - a place with dozens of endemic, at-risk species - to make room for yet another giant ship that will disgorge a bunch of people to shop for crap they could have bought at home while they try to get over their stomach-ache from the breakfast buffet.
They are, actually, goddamned evil.
And you are not visiting Mexico. You are visiting a mall. A mall that might be in Mexico. But there's nothing Mexican about it other than the people there are going to try to hard-sell you tequila until you get back on the boat and the town will close up shop until the next vomitorium of cruise-tourists splatter onto shore for the day.
There's nothing "sampler"y about cruise destinations. They're the same boring ports where you can buy the same boring coconut carved into the same stupid monkey that says "Mexico" or "Jamaica" or "Aruba" or whatever on your way to Senor Frog's.
Rethink your curiosity and wanting to learn more about something that is obviously and demonstrably responsible for the destruction for the ecosystems we claim to value as divers.
I am curious about other people and their experiences. People are interesting. But I am not that curious about people who happily just destroy things for no other reason than they pretend not to know better.
