whats the big deal about Rapper Common at the white house?

i was tripping at how so many conservatives but the tired fox channel are crying over Rapper at White House and they are digging at some of his past songs to make a statement, which as usual comes off racist and very loaded. as if every celebrity who has performed over the years never said or had anything on there records that might be offensive? Common has stayed in his lane and hasn't been edgy in years on record, he is a very talented poet, he is more of a actor now though than for his rapping these days. Common is a versatile rapper though and blends into any crowd. this is just something being started to get some folks to trip on Common when it ain't even necessary at all. Common writes songs that deal with everyday situations and he is cool with President Obama and the first Lady, they are all from Chicago, but typical Hate geared at a Rapper. same ole same
