I never tell you to show disrrespect to your family either,prophet mohammad (S.A.W) love his uncle abu talib so much even he is polytheist, but he never stopped even at his death bed to convey the shaahda to him.

what i mean, we can love and respect anyone but it doesnt mean we believe on what he believed.

again i suggest for you to study about the concept of " walaa and Baraa"

"Born optimist nothing can keep me too low for so long"
