There have been several responses in this thread which, in various ways, say that if someone loves you then physical attributes won't matter. They don't specify what sort of love. Of course, physical attributes won't affect the love of a parent, child, sibling or friend. I can still love someone as a friend even though I don't find them physically attractive. However, the original post was about dating and so, I presume, about the sort of love that includes a physical relationship.
A physical (sexual) relationship requires sexual attraction, so it seems illogical to say that physical attributes do not matter. I'm not referring to disability but to any physical attributes. For example, speaking personally, no matter how much I love a woman's personality (and I have some excellent female friends) I would not date her with a view to a physical relationship. This is not, of course, any criticism of women.
'True love' of an individual's personality does not create a sexual attraction. I can't choose to be sexually attracted to a woman just because I think she's a wonderful person. Indeed, some gorgeous guys happen to be heterosexual and don't find me attractive just because I'm male, but I don't let that make me feel bad about my gender.

Sexual attraction is based on physical attributes. We may feel that this is shallow, unfair and wrong, but we should not pretend it isn't so just because we disapprove of it. For example, I find red-heads very attractive and hairy bodies very unattractive. On the other hand some guys get turned on by hairy bodies and turned off by red heads. Some things that turn me off (e.g. a circumcised penis) may be considered strange or weird. However, this is not something that can be chosen just because on an intellectual level we might feel that it's shallow.
Sometimes it can hurt to know someone I fancy doesn't find me attractive because of some 'shallow' physical attribute. For example, I'm short (or 'vertically challenged' as the PC people might say!) and have found that some guys are turned off by that. That makes me sad, but I can't blame them for something that they have no control over.
There are posts in this thread that imply there is something wrong with a person who allows diability to influence their choice of who to date. Yet there is another thread here in which the posts imply that it is perfectly acceptable to allow race to influence the choice of who to date. Yet to me race and disability are just different physical attributes, so I can't see why the two threads seem to reflect such different attitudes.
Basically, what I'm trying to say is that some guys will find a disability a turn-off just as they might find your race or height a turn-off. On the other hand other guys (myself included) won't care about it. This is a fact, no matter how shallow or unfair we may think it is. The important things to remember, though, are:
1) a disability or illness is just one of many physical attributes like height, hair colour, gender, race, etc. that may affect whether others find us attractive.
2) if they don't find that attribute attractive they are not rejecting you as a person and it doesn't mean you are inferior in any way.
3) just because some attribute stops them being attracted to you does not mean that they are 'bad' people (unless they also treat you badly!).
4) there are guys out there who will find you attractive and who will want to date you.
