Religion is a very sensitive subject that should be addressed correctly, and any wrong, inaccurate, or vague word can easily be misinterpreted and send out the wrong message, sometimes a message that is the exact opposite to what you are trying to say.
The more important part of this is the style of the cleric/preacher/Mufti/daa3eyah/sheikh/Imam, whatever you wanna call him (I'll call him Mhaawesh here but you shouldn't) and I don't mean his clothing style or his hair and beard style, that's something I'd rather not get into at this point because I don't believe there's a uniform for a Muslim! I'm talking about his style of delivering the piece of information he wants the viewers to learn.
Let me explain further, suppose Mhaawesh here wants to talk about mercy, compassion, sympathy, kindness, or any other virtue, he wants to say that Mohammed (salla Allahu 3alayhi wa sallam) ordered us to smile at each other, he ordered us to visit our sick friends and relatives, to treat our children equally… etc. now what do you think is the best way for Mhaawesh to say such things? I'll tell you what: BY YELLING! Or at least that's what most of them out there are thinking.
How can you possibly talk about a religion of peace when you're yelling the whole time? Shouldn't you be doing what you're telling us to do before you appear on TV? At least smile at the camera for God's sake 7ajj Mhaawesh!
There's a big difference between talking on air as if you would be talking to a friend or a group of friends, and talking as if you're telling people off for doing something wrong. And if a non-Arabic-speaking person accidentally tuned in, what would they think Mhaawesh is talking about? Peace? Forgiveness? Being good to one another? I don't think so, and frankly, it's not the kind of thing I would want to spend my afternoon listening to, even when I do understand what he's saying, because if I wanted someone to yell at me I'd just tell my father about that time when guys had to lift my car up to get it out of the place I got it into, at least he'd be yelling for something I actually did.
And even in case Mhaawesh is talking about rules that should not be broken, punishment, sins… etc. this is not the way to do it, because a man of religion should be encouraging people to listen to him rather than scaring them away.
Try to see the difference between these two guys, with all due respect to all the shyoukh out there of course, the first one is an Imam in Morocco during Khotbat Al Jumaa (sorry about the video quality but you have to see this) and the second is Dr. Mohammed Rateb Al Nabelsi on a TV show talking about being thankful for God's blessings among other things.
