Rights are of essentially two types. Positive and negative. 

Positive right claims are that we are entitled to something specific. Things like access to healthcare, a decent wage, affordable housing, respect etc.

Negative rights on the other hand, are our rights to be left alone and unharmed in our pursuits. 

Negative rights can be rationally and morally supported while positive rights cannot.

Many things which may indeed be desirable are not rights. They are simply desirables.

Many of our societal problems today are the direct result of not understanding or appreciating this important difference.
