The latest Sunni scholars I used to listen to were non-Arabs..
The main ones were Deedat, Hamza Yousif, who I respect a lot, and Shaykh Ninowy. I posted a lecture of Shaykh Ninowy in our webpage:

As of the Arab Sunni lecturers, I used to listen to sheikh Mitwalli Al-Sharawi a lot.
And lately, I started to listen to the very moderate Sunni scholars: Adnan Ebrahim and Hasan Farhan Maliki. These two scholars are very popular among the Shiites.
Regarding the other point, which is related to the Shia stance from the Sunni/Shia Issues, This issue is not new. The Shiites have Hadiths informing them how to approach this issue:
Here is one of such Hdiths:
Imam Sadiq (a.s.) said:
عودوا مرضاهم، واشهدوا جنائزهم، واشهدوا لهم وعليهم، وصلوا معهم في مساجدهم
‘Console their sick ones, and witness their funerals, and testify for them and against them, and Pray with them in their Masjids’.
So Ahlulbayt (a.s.) want the Muslims to be united and reject any form of sectarianism.
Yes, we believe in spreading the teachings of AhlulBayt (a.s.) and their views. However, in the same time we call for Muslim Unity. As of the Shia/Sunni labels, It has been there from the beginning, and it will continue. However, this should not divide the Muslims.
