I don't believe this is the place for petitions.
I for one, am totally opposed to uncontrolled free movement for a variety of reasons including terrorist threats and will never support it.
However, I respect your right to believe otherwise. I would suggest ,however that you set up a petition on change.org, or a similar petitioning site.
It would be more appropriate and the tools are already there to get it off the ground with the minimum of fuss.
There are other petitioning sites set up already that you could also use . Best wishes and good luck.
