Is it sinful for me to cherry-pick what kind of da'wah I want to hear and accept? I don't enjoy and accept some of the 'ulama here in my country for their way of speaking or delivering the speech, even if it's true. I kinda disappointed by the traditionalist point of view and I want to start to build my own perspective to perceive Islam the way I really want to see and feel about it. I dislike the feeling of extremism that emerges every time I try to accept them, and so I stopped listening.
Actually according to Imam al-Ghazali it is obligatory upon you to build your own Islam out of all the pieces you can gather rather than trying to follow the opinions of others. So what you are doing is perfectly fine. If you are not satisfied with what you hear, that means you are intelligent enough to seek knowledge on your own and to surpass them in understanding. Become a scholar yourself.
I recommend reading Western scholarly works about Islam’s great scholars and thinkers, such as Imam al-Ghazali, Rumi, al-Shafi`i, Imam Malik and others then reading the books they cite, and you will find a whole new world open up to you.
