Yeah, i agree.. but for our actions to have an effect - we have to show that we actually are muslims. This way they feel that we do what we do because we are muslims, and not just because of culture.
So for instance i gave da'wah to a non muslim in my class for a little while, but it was only a 5min thing [i mentioned the points regarding tawhid, risaalah, and abit about afterlife all in one 5min package] - now that i talk to the guy, even if its not about religion - he might see me as a muslim instead of an asian.
We should also try to implement our identity as muslims, like growing the beard and wearing the hijaab because people will reflect on the fact that we're muslims and not just a culture. Which will warmen them to islaam insha'Allaah, but this can only be done if we actually show them we are, and give the message insha'Allaah.
