  I will agree with your post title, but not your explanation.
  Words are meaningless, unless they have actions too. The actions without the words can still be incredibly valuable.
  Would you rather have a parent who says they love you every day, but does nothing for you. Or a parent who doesn't say I love you specifically, but works hard to allow you to afford to have the things you need or want, shows up to your games/recitals/events, helps you with your homework, makes your favorite meals, etc. etc. 
  Sure in a perfect world everybody would be capable and willing to both say and do things to show their love. But actions are for more effective than words.
context: Many people have mentioned that people express love differently, and that’s true. That’s where the whole idea of love languages comes from. People simply speak different love languages, and knowing what their love language is goes a long way to making them feel loved. 
  An example… my love language is physical touch. My wife’s is receiving gifts. So what does that mean? I can hug, kiss, pat, or touch my wife until the cows come home, but it doesn’t have the same effect as bringer her a Kit Kat home from work, or giving her a binder clip (yes a binder clip… she kept that thing on her nightstand for years). Conversely, she can get me the most thoughtful gifts but I don’t feel nearly as loved as when she jokingly slaps my ass ass I walk by or briefly puts her hand on my back. 
  The point is we can screaming I LOVE YOU in our language but if it isn’t theirs then they just don’t hear it. >
  
  I don't think love between two grown adults can be compared with the love between a parent and a child.   The issue here is parents failing to understand the love language that their children needs, and as you said you can scream "I love you" but if it isn't in their love language they just don't hear it. >
  
  I’m not comparing a relationship between two adults and a parent and child. They are both dependent on recognizing the others language.  Properly expressing that love is definitely key, but speaking someone else’s love language is super hard to do. It’s also important that we recognize what others are doing to express their love. >
  
  As I have mentioned before expecting a literal child to be aware and understanding about your emotional reservations while not cluing them in about it is asking too much. You can't expect a kid to have the same level of understanding as an adult. And frankly if you absolutely unable to be flexible with how you share your affection or feelings you probably shouldn't be a parent. >
  
  No of course not. But as the child grows hopefully they’ll be able to recognize all those things their parents did was in fact love. Granted that doesn’t do a whole lot in the moment of youth, but that’s where the parents should understand and adapt to the child. Sure I’ll even agree that if you are completely inflexible that will make you a bad parent, but flexibility is not the easiest of things for the best of people. Especially when it comes to raising kids because nobody is perfect at doing that.
