Strokes do not necessarily cause cognitive defects or impairments, but gross and fine motor control (which includes verbal and written communication skills) frequently are adversely effected (e.g., motions become tremulous or speech slurred). If Roy slowed down when working out messages and double checked what he's typed prior to submitting messages, written communication skills might begin to gradually improve, maybe only a little, but maybe quite significantly, too. So, yeah, it at least seems worth a try.
Obviously, Roy is capable of expressing himself in writing; however, to deny problems exist with his writing(s) is to embrace falsehood. Certainly no caring or thoughtful person would want to deny Roy the opportunity to at least try to better himself here, right? Yet that in essence is what one does by telling him that, "as is", everything written by him is just fine and oh so wonderful. Such simply is not true! Words are going missing, being altogether left out of what he's attempting to express, and word order is flipped regularly. The honest to goodness, naked truth about all of that is that such mistakes can make for a difficult and sometimes incomprehensible read.
Wanting Roy to remain in a lower functional state is cruel, especially if improvement truly is possible. Such might not be possible, of course, but if it is, then feigned love and pity certainly is not what is called for because hypocritical Band-Aids like that don't really treat an underlying condition. What Roy instead would need here is some good ol' spitshine honesty. Sure, at times such can come across as insensitive; however, unless Roy (or any other person similarly affected) is "pushed" like that by being confronted with whatever seems to be a problem and provided with an opportunity allowing for correction, then any improvements (ranging anywhere from partial to even full restoration of skill) likely are to be agonizingly slow going and might not ever occur at all.
Such "encouragement" compares to that seen with parenting, teaching, or job training, and, of course, is or should be matched to age, mental and physical skills, degree of impairment, etc. A cursory perusal of information available on the Internet (in such fields as Neuroscience, Psychology, or Speech Pathology/Therapy) will attest to this; however, for verification or for additional information, one should seek professional counsel at a local clinic, hospital, etc.
Absent that, for Roy simply to ask a family member or friend to proofread his work -- without making corrections for him, but only pointing out errors -- may help a bunch. Neither he nor anyone else will ever know, though, unless a salvation plan as such is worked out and at least tried. After all, faith will have no effect on the keyboard. And should "as is" be the best Roy is able to do ... well it's simply up to others at that time to rub their eyes and smile out a response akin to, "Um, Dude, ya wanna run that by me again, please?"

P.S. Regarding censorship ... this is not a game to me, and things are as previously stated. (Moderate out this P.S., or the whole post, if you so desire. Either way, I will not be posting here any more. Tried to startle and stimulate the intellect, and tried to laugh, too, but fighting is what's desired by many it seems, and that to the death. A grotesque, retarded, senseless, and most shameful undoing of joy ... and of life itself! 2 + 2 = 4 = my opinion? MY "truth"? Uh-huh, NOT, but whatever. Bye.)
