Now we know that your Islamabad upbringing made no difference. 
At least when I mention anything I give facts and figures to justify myself, and do not discriminate between Karachi or non-Karachi players, as one can see in my post that when I mentioned low averages of Pakistani players compared to Sarfraz or Fawad, I did not exclude Karachi players with lower averages or players who had high averages and are not from Karachi (I included all players, regardless of where they come from). Actually, when I mentioned Umar Akmal lower average than Fawad in ODI, I also mentioned that Umar Akmal SR is higher than Fawad in ODI.
Actually, when Misbah was getting discrimination (by Inzam), I wanted Misbah to play for Pakistan team. Same about Abdul Razzak or Afridi … so, my concern is not Karachi or Punjab players, but I would like to mention any discrimination that happens in Pakistan. Unfortunately, since players who are getting discriminated are mostly from Karachi, it seems I mentioned only their names.
As far as your post is concerned, you declared players (Sarfraz and khurram) deserving or undeserving according to your own opinion (or your own biases or convictions) without any reason or records to justify that, and you picked only players from Karachi (even though these two players have higher first class average than most Pakistani players), show you have your biases and discrimination too.
You should know that … even though wicket keeping performance is not only about how many batsmen a wicket-keeper dismissed, as that depends on how many chances wicket-keeper gets to dismiss, and that means quality of bowling in team wicket-keeper playing, and wicket-keeper like Akmals have better bowlers in team they play … when selecting, management can decide on various factors, including catches, stumps, and catches or stumping chances a wicket-keeper missed. Kamran Akmal was notorious in missing catches and stumping chances.
Anyhow: If we only check catches and stumping figures of wicket-keeper per match, and their batting averages, than Sarfraz has batting average much better than most Pakistani batsmen, and has shade better wicket-keeping figures than Adnan Akmal (in my post, I wrote that they have similar record … as I do not discriminate) … though Sarfraz has slightly lower figures than Kamran Akmal. Here are records … (you can check if you want to)
Sarfarz … 318 catches and 26 stumps in 97 matches … or 3.55 dismissals per match …
First class batting average = 40.33 (higher than most Pakistani batsmen playing test for Pakistan)
Adnan Akmal … 392 catches and 19 stumps in 116 matches … or 3.54 dismissals per match …
First class batting average = 25.72
Kamran Akmal … 661 catches and 53 stumps in 191 matches … or 3.74 dismissals per match …
First class batting average = 33.69
Note: Sarfraz batting average is more than most Pakistani batsmen and that is plus point, as he deserve to be in team even as batsman.
