Then I'm sure you can provide clear cut unambiguous information.
Since you can't, lemme ask
Are Shi'as true Muslims?
Are Ahmadi's true Muslims?
Are sufis true.Muslims?
And why there are so many school of thoughts within Shi'as and Sunnis? Like Hanafi, Maliki, Hambali, Shafi, among Shi'as twelver and others?
And what is your position on LGBT issue?
A muslim is someone who acknowledges, accepts by heart and testifies by tongue that there is only one True God (Allah) Who is unlike His creation and that He is the creator, sustainer, cherisher and controller of everything that exists, that He had sent prophets and messengers and the last of them is Prophet Muhammad (peace & blessings of Allah be upon him). After such a testimony a Muslim can NOT reject any of the fundemental tenets set out in the Quran and sunnah for example - Quran is the word of God, alcohol and pork are prohibited, adultery is prohibited, hajj, zakat, 5 times daily prayer, existence of heaven & hell, Angels and jinns etc etc.
There are spectrums within shiaism that reject fundemental islamic principles i.e some of them malign the companions of the prophet and give their imams attributes of God. So Shias are NOT a black & white group.
There is a spectrum and many fall within framework of islam while many don't. The claim of any groups must be judged based on Quran & sunnah whose texts are very clear, preserved unadulterated for 1400 years, and whose compilations are in singular editions unlike other religious texts.
Qadiyanis are NOT muslims since they reject the finality of the prophet Muhammad (peace & blessings of God be upon him). Again just because somebody claims something, does NOT make him what he claims. Eg.
if somebody claims he is an american citizen but does NOT have american passport , he will be treated like a foreigner non-american by US autorities until he/she can prove by vlaid documents that shows he/she is an american.
Sufis are are NOT a sect. They are a spectrum within sunni school of thought and many fall within the framework of islam. Get yourself informed about these terms before making your flawed conclusions.
As I said you are utterly ignorant about islamic terms & narratives. Hanbali, shafi, maliki, hannafi are NOT sects BUT schools of law of sunni Islam.
They also share the same fundemental understanding of islam. The difference has to do with fiqh i.e body of islamic laws deduced from the Shareeah . Shareeah is the body of revealed laws found in the Quran & sunnah and it lays down basic principles and guidelines. Fiqh concerns itself with how those principles & guidelines be applied in a given circumstance. Fiqh can vary from place to place and circumstance BUT islamic principles do NOT.
Fiqh does NOT concerns itself with basic fundemental tenets like concept of God, messenger, existence of heaven & hell, angel, jinns, 5 times daily prayer, hajj, zakat, prohibitions laid down in Quran & sunnah etc etc. These basic tenets are aqeeda issues and are set in stone and all 4 schools of sunni islam agree on those issues.
For example the 4 schools agree that alcohol is prohibited in islam but there is a difference of opinion regarding the number of lashes a offender can be subjected to.

The 4 schools agree that act of sodomy is punishable offense but since the companions of the prophet themselves differed on the best way to punish sodomites, the various schools and scholars also gave different rulings on how to punish them.

As for LGBT, Islam does not even recognizes such terms and identities based people's sexual desires and preferences. The only valid Islamic way of expressing ones sexual desires is via islamically sanctioned marriage between a man and a women. The act of sodomy is the most gravest sin one can do and is punishable by death under islamic law following state sanctioned due process. The people who promote LGBT perversions and tries to normalize it are the worse possible evil of humans out there. That's my view as a muslim.
