A lot of kids don't like textures, and my son was one of them. As someone else said below, the tongue motion is not something they all understand at 1 year. Chewing is an entirely different skill/motion/feeling and some kids just don't "get it" as early as other kids. I tend not to worry about things like that because they all do something "early" and other things "late" - walking, talking, teething, potty training, sleeping through the night. Since you can't control his eating, I'd stop making it any kind of battleground. It's more important that he get lots of nutrition and that he develop a taste for different flavors. Keep offering other foods (watching for choking hazards as others have suggested) and make meals a pleasant experience. Show your pleasure in your own foods, and eat with him - comments like "Oh these blueberries are so delicious" will get you farther than trying to force him.
I work with kids with all kinds of sensory issues and a lot of them have trouble with solid foods at much older ages. We just supplement with a comprehensive liquid supplement that meets all their nutritional needs, and then the other foods they eat are a bonus. We do this with preemies through feeding tubes, older kids dealing with malnutrition, and many kids with sensory and swallowing problems (those can be anatomical or connected to things like being on the autism spectrum), and those who are just too particularly or too fussy to sit still for long enough. So we know that essential to be on solid foods from a nutritional standpoint. Of course we want them to get to that point, but the main thing is to keep then growing and getting the necessary brain development and hydration until they grow into it, mature, develop a taste for foods, or get over their aversion to texture.
I think you can wait this out. Other than the convenience of having him eat what you eat, there's no huge rush to have him move to solid foods as long as his nutritional needs are met. You want him to develop the small motor skills such as picking up foods and putting them in his mouth, and eventually be able to use a spoon himself. So encourage him to do those things but continue to help out. He does a spoonful, you do a spoonful.
I saw a photo someplace of parents who use an ice cube tray to display different types of chopped up foods in different colors & tastes & textures. You could try a version of that (hold on to it so he doesn't dump it!) and put baby food or pureed foods in some of the compartments, some yogurt or applesauce, (so it doesn't all come from baby food jars), and then some other cut up or small foods in others. You don't have to do all 12! That's probably overwhelming! But a few pieces of easily chewed or "gummed" foods might be great - cooked carrots, peas, avocado, sweet potato, watermelon, a few berries, small French toast cubes (they are soft), etc. You don't have to go directly to very chewy foods like meat, but cheese cubes and some cheerios and small crackers are okay. Make a game of identifying the shapes - peas are round, cheese cubes are square, spaghetti is a line, etc. Or mention the colors. Do this not to drive home the learning, but to make conversation and show him all the aspects of the food - taste, texture, smell, shape, size, etc. When he's done, take it away. Take him out to eat when you can and let him try things from your plate
I think, barring any major developmental issue, he'll catch on. Meantime, if you turn it into a fight and he becomes stubborn or even fearful, it will take that much longer to get him to try things. If you're patient and as long as he gets nutrients, it should work itself out. Don't be intimidated by people whose kids ate much earlier - I guarantee you, you child is doing something else that their kids are not.
