the characteristics that lil b embodies are influenced by things that most rap fans don't have a connection to and can't relate to, so honestly it's not surprising that it's hard for a lot of people on here to get into.
it's obvious that lil b takes from here-and-there (punk rock, gangster rap, electronic music, etc.) and makes his own little thing out of it. if gangster rap is the only one of his frame of reference that you can relate to, of course the other parts will throw you off because you're not checking for them and never will.
it's not his fault and it's not your fault, and it's not even the huge moral conflict some people make it out to be when you look at it objectively, because "hoes on my dick cause i look like jesus" or "i got AIDS" is honestly a mild statement in the context of punk rock and even contemporary art. it's even ok (and common) to not be good at your instrument in punk rock, because that's not the point. the artform isn't based on having the highest level of technical acumen and neither is lil b's raps.
you may not realize it, but you're mad at lil b for having more diverse influences and frames of references than the artists you're checking for. that's the root of it.
