These things mostly happen in subcontinent.
I don't see these things happening much in Africa or Middle East.
So, definitely a cultural issue and not a religious issue.
I don't think it's cultural, especially if we talk about the Islamic code of life taught in Pakistan.
It's the indoctrination of wrong Islamic theology into masses by JahiI and/or cunning Mullahs for their personal benefits.
The two major issues are, the Islamic priorities are taught totally in the opposite order. Things that should be the HIGHEST priority are depicted as if they don't even exist. And things that are the LEAST priority are portrayed as if, this what Islam is all about.
Take for example, the 5 major lessons from the life our prophet (saw), PATIENCE, TOLERANCE, FORGIVENESS, GOOD ETIQUETTES and LIVING THE OF LIFE HONESTY - notice that hardly any Mullah focusses on these distinctions.
Now look the opposite spectrum. Growing a long beard, having your shalwar placed above your ankles, various wazeefas, high emphasis on "tilawat" (without knowing the meaning), and various other "short cuts" etc is heavily focused on.
The combination of two has resulted in the creation of a big chunk of people who are
Munafiqs (look all Muslims from appearance but corrupt, and dishonest to the core from inside) that are divided into blood thirsty intolerant groups of Shia, Sunni, Wahabi, Ahle hadeeth, Deobandi, Brailvi, Qadri, Chisti, Sabri, harri pagri, kaali pagri, labaik, Ashiq, Gustaakh, etc.
Our Mullah in the subcontinent has absolutely no control of any sort by anyone as whatever the HECK he wants to preach to the masses.
And the result is front of you.
Some idiot makes post on Facebook that reciting surah kosar and blowing the air on the electricity meter, will result in lower monthly bills no matter how much of an electricity you use.
Such a post gets over a 100K likes.
An idiot says, Sheikh Abdul Qadir Jilani met Allah and stopped him from throwing a man from being thrown into hell fire. The listeners start dancing in joy with Qadir Jilani slogans going through the roof.
The guy is singing Qawali on Nori Bori wala's mazaar and starts cussing mom/sister of those who won't dance on his music tunes. The crowd enjoys a huge laughter and indulge deeper into "dhamaal".
100 and millions of Rs were collected in a matter of a few days to secure the potential bail money for Mumtaz Qadri while a huge chunk of the nation is under the poverty line and genuinely struck hard by the financial squeeze and inflation)
There is hardly any good Islamic scholars are left in Pakistan, as we are the mercy of these munafiqs who are calling each other kafirs and worried about the length of beard.
In Arab world has lots of problem of their own, but perhaps they are not as deeply divided into bloody thirsty group as we are. They don't have armies of these unleashed Mullahs that get the general public astray.
In subcontinent, especially in Pakistan,
We need to upgrade our Islamic teaching and Islamic Guidance to be a uniform mandate for the entire country - especially for the younger generation and to our kids.
And that is,
To prove your Muslimness and your Islamic faith to God and his prophet, you must start with two things.
1 - You MUST live the life of honesty of a law abiding citizen where you must avoid, haram khori, rishwat khori, jhoot, dhoka, zulm and intolerance towards other faiths. You must have good etiquettes and you should be patient, tolerant, generous and a forgiving and merciful person.
2 - You should be someone who tries his best to offer 5 daily salah on time with congregation, during the entire course of your life. If you can't do it, then yes, it's a matter between you and your Lord; however, don't preach your brand of Islam to others.
If you can't meet the above two conditions, where you can't live a peaceful and morally cautious life with honesty to begin with, don't consider yourself to be a "PROUD MUSLIM".
