Question to "Quranist" and Sunnis defending them

As salamu aleikum to My Muslim Brothers and Sisters

I know my Text sounds Like a Question but it should be an discussion, so If Somebody that I described Sees this, we can talk gladly. At the end of My Text are Prooves.

1. Why do today so many "Sunnis" excuse the Rejectors of the Sunnah, wich are per Ijma Out of Islam? And I also notice a pattern: it is often precisely those who cannot explain Tawḥīd, ʿAqīdah, al-Walāʾ wal-Barāʾ, and the fundamental foundations in general, but they end up constructing their own religion (may Allah protect us). Now to My second Point

2. Why do so many today Just make their own Religion, own understanding etc. Thats complete against the Quran and Sunnah, I think we all know the Verse where Allah says that we should ask those who know.

Evidence that a Muslim has to Accept the Sunnah and that Sunnah Rejectors are Kuffar, from Quran:

1. [4:64-65]

2. [24:54]

3. [53:3]

Evidence that we should accept and acknowledge Scholars:

1. From Quran, [16:43], [21:7], [4:59] and more

2. From the Sunnah wich is to be taken, as prooved already before, (sunan abu dawud 3641) and more

3. From the Salaf, wich got praised by the Prophet ﷺ in Sahih Al Bukhari, (Muhammad Ibn Sirin Said: "This knowledge is religion, so look carefully at whom you take your religion from.")
