Am I wrong to not want to let my kids have facebook?

[Amanda]

I'm only 21 and don't have any kids yet. However, my sister (who has 2 kids) is already talking about how she can't wait for her children to get Facebook (or whatever social media site is in style then) when they are 9 or 10. I, personally do not agree with this for many reasons. I think there are so many opportunities for sexual predators to find children on Facebook. Also, children can bully each other online which is dangerous and sometimes worse than bullying in person. Lastly, I know from my own experience that people can be rude on Facebook. For example, if a link is posted with like 200,000 likes and comments, if you comment with a differing opinion people can totally BLAST you and people you don't even know can send hateful letters to your inbox. Adults usually know how to deal with this BS and let it roll off their back. But kids?? Something like that could make them suicidal. I think when I have kids I will be a very protective parent and not allow my kids to have Facebook or become involved with social media until they are 17 or 18. Do you think I am wrong for feeling this way? Thanks!!
