I was thinking of starting a petition against a big sex store that was opening

[Ƹ̵̡Ӝ̵̨̄Ʒ]

up in the city I live...? The reasons i've decided to start this petitionmainly is because it's near the biggest park in the city where most of the children with their families come to everyday. There is a huge sign thats up labeled sex shop. So I need some ideas because I have never started a petition and im not too sure where to start... I need some ideas and help... thank you
