Would you call a non-Muslim your brother? Love for sahaba is proven from the Qur'an and sunnah and is part of our aqeeda. Love for ummahat-ul-mu'mineen رضي الله عنهن is proven from Qur'an and sunnah and is part of our aqeeda. Shi'a curse and insult both and even say that 'Aisha and Hafsa رضي الله عنهنا were responsible for killing Rasoolullah . If you still have love for people who do such things, I can't say anything to you. May Allah guide us.
