I don’t understand the reason behind it. Is it so you can have your friends comment on the post talking about how they disagree as well?
I have never done that on my Facebook or here on my blog. If I come across something I disagree with I let it go because I wouldn’t want to personally be a part of giving that idea or person anymore publicity than they already have.
I know they have a right to feel, say, post, write anything they wish however I have a right to choose not to give them help in spreading their ideas/ information.
PS. This is about me continuing to deal with my feelings from earlier, See “I really don’t know why that post made me so mad” in the random stuff/rants tab of my blog for more info if you’re interested.
