I just removed the Facebook share icon from all my blog postings. I have no desire to have anything connected with social media companies on a webpage or blog article that I control.
If you must share somewhere, however, it is easy. Just click on the title of the article that you want to share, thereby bringing up just that article in your browser, and then grab the URL for that article in the URL field of your browser. You can then share it anywhere. Knock yourself out, but I am no longer placing icons of social media companies on my blog or any other content that I control.
