Of course I do, Henrin. As a disabled person, I know how vital it is that such protections exist. It's not lost on me that it has only been 25 years for people like me, both seen and unseen disabilities, who have been protected.
A society has many components, but a substantial portion of our society revolves around private enterprises open to public commerce. A libertarian sees an individual transaction located in a single store, which happens to be denied on the part of a person exercising their "right" to determine who shall get his/her labor. However, that denied citizen sees this as a series of individual transactions which culminate in a large portion of their lives. Denied in a business which provides birthday cards, denied in a business which provides coffee, denied from a business which provides the groceries, denied...denied...denied. His rejection is multiplied time and time again, and his fellow citizens know his denial and the reasons with which it happens. This in turn affects how the citizens not denied view him, reinforcing the already negative views which had been pushed onto his person.
The libertarian presumes that men are rational creatures, willing to use cost/benefit analysis. This cost/benefit analysis incentivizes business to cater to the needs of substantial markets, thus, obviously the minority's interests will be secured. But men are not rational creatures. They hold their prejudices and ensure they stick. If one is a member of a group which is largely despised, they will not be treated well in a system in which a de jure non-aggression principle is adhered to.
Through this lever is the flood to which the individual becomes the scurge of his society rather than a valued member of it.
To the man who is part of a non-offending group, he has freedom and liberty. He can reasonably do as he so chooses and by some manner of virtue of his own gifts, have the opportunity to live a decently healthy and happy life. The person who is part of an offending group, on the other hand, can not claim the same.
Libertarianism is the comfort food for the solipsistic unoffending bourgeois democrat.
