I find your comment quite disrespectful and in poor taste. As a former illegal immigrant, I can assure you neither I or my parents were unskilled, uneducated, willing to commit crime, or not contribute to the greater good of society as you put it. Desperate times call for desperate measures, and like you said it yourself, the current immigration process is insane and barrier of entry prevents good people from migrating to this country legally. I don't blame my parents for making the tough choices that they made; they lived in fear of getting deported, not finding a job, and not being able to support their kids. And the part of about contribution, we paid our share of taxes without getting any support or assistance from the government for years until we became legal immigrants, do you find that fair? It's insane to make such inane comments and paint people with wide brush strokes.
What about peaceful protests? I don't think having a sign should warrant removal from the rally, I though that's what free speech was all about.
