Religion is not door to door sales campaign. Follow Islam properly and stay away from haram and you will be able to face Allah (swt). Tableegh is not going door to door and "trying" to convert people. Then you give them some brochures with hadith with the same Nabi (pbuh) name on it. Do you have any idea where those brochures end up. Those kafir people throw it in the garbage. The tableegi people like you get gunnah for it because you were responsible for giving it to them.
Now let me ask you a simple question. If a person is injured and about to fall, would you not give that person a hand and help them up? Yes, you would. Anyone would. Just like that, if any one of our muslim brother or sister is going in the wrong direction (clubbing, drinking, eating haram, not praying etc) then its our responsibility to explain them why this is wrong for them and how will they face their allah (swt) on the day of judgement.
Then that person will look up to you and will bring many of them friends to you. This is where you teach them the beautiful religion of Islam.
Brother you have good vision but your technique is flawed.
