Dear Brother,
You may not believe that Islam has divisions or "sections", but the reality as we know it is that Muslims are divided, no wonder that you posted all Sunni related videos. On the one hand you post exclusively Sunni videos, and on the other, I am being blamed for trying to create divisions by posting Ahmadiyya videos. I am inviting people of all groups to post interesting videos to share differences and learn from each other. Yet I am not the one diverging from the topic by posting videos in an attempt to counteract relevant posts made by the other person.
Converting to Islam of the Ahmadiyya interpretation is unique among the Muslim world. When someone becomes an Ahmadi, he (or she) does not just become a Muslim, he also ties himself to Khilafat and to the community (just like in the early days of Islam). There is a powerful emphasis in the connection with the living Khalifa of the time. Without Khilafat, there is no Jama'at. In other words without Khilafat there is no Ahmadiyyat. That is why when someone becomes an Ahmadi Muslim, discussing their conversion stories whilst leaving the "label" Ahmadiyyat or "Khilafat" out is almost impossible.
On the other hand, there is the conventional Sunni Islam (note: Ahmadis are Sunnis though). From the point of view of the outsiders, Islam=Sunni Islam, on the simple basis that it is the majority. So when someone becomes a Sunni Muslim, there is no reference to Sunni thoughts or views, just Islam, although on the inside they are Sunni.
These two points that I've made above should be enough to point out that your argument that there should be no "labels" in the videos e.g. Ahmadi Muslim, etc is based on unfair and unjust grounds. Your looking at two vastly different worlds with the same pair of glasses, if that's the right phrase to use.
