The great thing is I can have my opinion and you can have yours. They are both just opinions as you know no more than I do on the subject. Hopefully sales will pick up this Holiday season!
There's a big difference between presenting them as opinions (e.g., "The two $100 off sales were timed right before Christmas and Valentine's Day, presumably as loss leader items for these retailers.") vs. facts (e.g., Apple is giving incentives to discount the watch). Perhaps you ought to be more careful with your words and people will be less likely to call you out.
