I think it's sad. I don't think she has even begun to deal with her son's death. She is so intent on finding a culprit and will associate herself with anyone that will listen to her plight. I didn't know that she had met Chavez. Bad move, it shows her desperation and lack of sound judgment.

Chavez doesn't only hate the current administration, he hates "los yanquis" and everything that stands for democracy.
It's possible that she may be doing some of what she is doing in order to avoid dealing with and accepting the fact that her son is dead. Maybe there is guilt, pain, etc. Who knows? I feel empathy toward her because she lost her son. I don't approve of the way she has gone about it.
I'm a
strong believer in fighting for our beliefs and important causes. You just have to be careful who you choose to associate yourself with and whose support you seek. Those choices make all the difference between having credibility or appearing like a lunatic. IMO, at this point, she has lost credibility and I think that's why many find her annoying.
