If rotary engines are so great (I am not saying they are not), then why does Mazda only offer one vehicle in their lineup with one? Why doesn't Mazda differentiate themselves from the pack and offer at least a few vehicles with rotaries, if not a rotary option on all of their vehicles?

Because the rotary isn't so great. When Mazda's were first introduced into the states all models had rotary engines. They are not as fuel efficient, create much more emissions, are finicky and need to be tuned exactly right and blow expensive seals compared to a piston engine. The first gas crisis hit soon after they were introduced and known for their bad fuel economy they couldn't sell the rotary.
I've owned two 3rd Gen RX7 twin turbo's and they were always at the dealer getting repaired. Neither one made it past 90,000 before the engine was shot. But they put out a lot of horsepower for such a small displacement engine and are lighter.

Mazda rotary engines are for gear-heads. They require attention and habits unfamiliar to us in this day in time to maintain a running car. You have to keep motor oil handy and top off every other fill up, you have to rev to 3k-4k rpm before you shut it off and let it run for a while, or it will flood, it burns the most expensive gas, if you do not follow procedures in starting and cutting off, like running to the drug store, it will need to towed to the nearest Mazda dealer. That being said, the rotary engine has character and impressive performance for such a small displacement. If Mazda were to place this engine in the majority of their cars, it would be a customer, JD Power, Public Relations nightmare because a rotary engine is high maintenance and not as reliable in day to day driving, like a Mazda mzr motor housed in the 3, Cx7, Tribute and I believe a similar version in the Miata.

They do not put rotaries in all of their automobiles because rotary engines are more expensive than regular engines. This is a large part of why the RX7 and RX8 are their most expensive cars in the lineup. Also, most people are unfamiliar with rotary engines and it would appeal to enough people to generate as many sales as Mazda is currently getting.

The motor isn't economically feasible for the entire line up.
The motors do use oil and are extremely powerful. The racing world puts these engines in classes with much larger motors as competition.

The 2 most important reasons are poor fuel economy and high emissions.

Its impractial, they cost a fortune and are not good engines to start with + it would be impossible to make them in a diesel aswell. Triangle pistons and all that.
