You can say you don’t like things or that you do, you don’t have to end it with “Sorry” or “Just thought I’d share!” or anything else. ESPECIALLY ON YOUR BLOG. You have a right to say whatever the fuck you like, whenever the fuck you like, BECAUSE IT’S YOUR BLOG. You don’t need to justify or apologize for anything you decide to post.
You don’t have to feel bad for sharing your thoughts. They’re just as valid as anyone else’s.
