GIVE BACK RM 100

A few Malay Muslim elders give back Appreciation Money to Penang State Government because they worry that the money is coming from sin tax. When the somebody challenge the opposition to give back their monthly allowances as well since that might come from sin tax as well, the reply is that their allowances are coming from government taxation and not sin tax. I am pretty confused about that. Not really sure how the taxation system works. My question is how to differentiate between normal tax and sin tax. Do they have a separate account for sin tax? Can’t we assume that all the money coming from sin tax will be used for non-Muslim? If the Appreciation Money is coming from sin tax, why can’t the assemblymen monthly allowances are coming from sin tax as well? Is it really the types of money that matter or it is merely a political game?
