Assalamu Alaykum,
We must have patience and talk kindly to people and explain to them their Deen properly.
Islam is complete, Alif to Ya ( A-Z ) and is perfect. It is for us to implement it all, in totality.
The foundations that people have, are unfortunately not sound!
Niqab, big beards, means nothing, if the person's Aqeedah, belief in Allah, obedience to the Prophet 
, clinging to the Sunnah is not present ! or has problems. You can go to any department store or shopping place in the West and see a man with big white beard near the time of 25th December! He or even She, has a good beard, although it can be easily pulled off!
Likewise, there people who look from outside pious and good, but, their hearts are of stone. Only Allah knows what is the reality of their condition.
The worst thing is that of Shirk, Kufr and Bid'ah.
This is why, we must always make sure our own beliefs and that of those around us is correct. -
Here, knowing Tawheed necessitates knowing Shirk. The Major Shirk, which is associating partners with Allah and the Minor Shirk, which is Riyaa' Showing off.
Then there are the sins which is linked to Riyaa', which is arrogance and thinking that you are better than others. Jealousy and Envy in the haram! Gossipping and backbiting!
These things damage people's behaviour and character, to the extent, it re-enforces a culture of such problems! whether a group culture or on a widerscale of similar behaviour. That is why, often you will not just find one person who behaves bad, but others who are close to this person! Astaghfirullah Al Azeem.
Likewise, the same can be said about those who are humble, kind and honest and who think carefully about each and every word they hear, they say and think!
None of us are perfect, but we must emulate the one who was the most perfect, as much as we can. Step by step, our beloved Rasul Allah, Muhammad
. The Al Amin, (trustworthy) the Seal of the Prophets! THe one who had the best character! The best man to have ever walked this earth!
Please, my dear brothers and sisters, we need work hard on ourselves. There is so much we need to do! How can we spend our time doing futile things and wasting our time? Before we point our fingers at other Muslims, lets point them at ourselves, and improve ourselves..
If we wish to help others, the beginning point is to help ourselves. We need start learning Islam properly and purely. Memorise Quran and Hadith, understand it from the way that the early Muslims understood! Stick to the Ulema who are known for their wisdom and adherance to the narrations and beliefs of the early Muslims! Such as Shaykh Muhammad Nasir ud-Deen al-Albani, Ibn Baz, Ibn Uthaimeen (rahimahumullah). They were great pillars of knowledge among us.. and their students are alive today and around the world and who teach and are full of wisdom. Their books and many lectures are translated.
These days, people turn to the lesser known or even non-scholars for their learning. Or from those who are totally opposed to the way of the Quran and the Sunnah! This is the reason for the failure of the Ummah.
Allah help us, guide us to the Straight path, and make us amongst those who are loved by Allah and amongst the best of his slaves, Amin
