I'm not too fond of the policy myself, ...but I do not have a say in it, ...and don't expect to have one.
I think it is a slippery slope one climbs when one starts dictating what one can and cannot say with regards to political dissent. I think this situation however is a unique one, in that Venezuela has a history of foreigners trying to undermine it's government. Foreign agitators stirring up unrest and attempting to both undermine and overthrow the legitimate government of Venezuela. It diid not succeed the last time, and I believe those who tried before, have not given up and will attempt another means to accomplish their same ends. I think his actions are designed to curtail further attacks on his government. The fact that it is directed towards foreigners is at least somewhat of a small comfort for his citizens. When you start banning the right to free speech among your own people, ...then there is a problem.
