Different religion different punishment lor. Don't like don't convert. And if you're Muslim, don't like, then bear with it or just convert lor.
Islam doesn't stop you to go convert your religion if you want to, it's better you convert if you feel that the punishment is too much too handle. Or rather, stay away from vices of the religion itself.
It's the same with some Hindus piercing their bodies for Thaipusam, and Chinese(not sure which religion) burning paper money during certain periods of the year (this contributes to air pollution, harmful for EVERYONE not just the people within their own religion).
So y'see, no need to say Islam rules are barbaric, it's just much more exposed in a negative light nowadays due to western media. What I see is that, there are certain extremists of the religion (public stone throwing, the cutting of a guy's private parts due to fornication), THAT is unjustified cause it results in death and it's murder whichever way you look at it.
This article, however, is punishment from a Muslim country to MUSLIMS. Do people of other religions face this? No.
