A past of discrimination, current time and the word conspiracy theory

I think that we need to look real hard at how the word conspiracy theory has been being applied, as well as look to see how it has been used weather it be to brush under the rug, cover up or just downright lie about current events. Also the fact that our association with believing in a conspiracy theory as a bad thing(and stereotyping). Also, it used to be a "Conspiracy Theory" to believe that the earth orbited the sun and anyone who believed otherwise was criminalized and their science driven underground. Just as we see today. Do you think that it was right that they mocked Copernicus and Galileo? I don't. I guess the word conspiracy theory is being applied today in the same way blasphemy was all those century's ago. We haven't changed much at all have we now?
