Social networking bit my Ass

I have some bitchin' to do, so for the avid readers out there. Shut up and listen. Quit being so f***ing sensitive. Lately my wife and her sister have been fighting. Well as of the last couple of days, they have been working on trying to make amends. I thought that was great. I want them to get things worked out so life can go back to normal. Unfortunately, I vented in frustration on facebook and it was all taken the wrong way. Most of my rants are never directed at anyone in particular, especially on such a public forum, they are just there for me to vent and feel better. Most of the time my comments are liked and agreed upon by many of my friends, but for some reason lately, a few people have been taking them too personally. Now because of this, my sister-in-law is taking my comments personally and blaming my wife for them. I never once directed anything at her and even if, she should not be blaming my wife for it. We are separate people with separate thoughts and opinions. I mean no ill will towards anyone in my life, but as everyone else, I get frustrated and use public forums to vent that frustration. I never direct it at anyone in particular and never mean anything personal by it, just my way of getting it out so i don't go crazy. If she wants to be mad at me though, fine, I can take it. She doesn't need to get mad at my wife though for things I said, especially when I didn't say them to anyone specifically. Now I feel bad because I am being blamed for messing things up between them when I feel I did nothing wrong. All I ultimately want is for them to get along again and for things to go back to being the way they were. We all know though, that things will probably never be the same.
